On many stereomicroscopes with achromatic objectives the center appears to be in
focus and have slighter greater magnification than at the edges. This is the
effect that "plano" objectives solve. They have the ray tracings of the lens
focusing in the same plane so the image appears flat. Sometimes increasing the
magnification reduces the effect or using a iris diaphragm - neither is a
"solution" to the problem.

   Some manufacturers do not offer alternate lenses for their microscopes and
provide a plano-objective with the microscope - but usually at a slightly
elevated cost because of the extra glass and engineering that goes into the
lens. The total microscope may be less than the Leica/Wild but for other
reasons.

   Hope this helps.

   I recently purchased a Wild M3Z stereo microscope with a Wild 1X
objective (PN 411589) and Wild 10X eyepieces (pn 445111).   It
appears to be in excellent physical shape, but it has two issues.

1.  When viewing a flat object, the stereo image is not flat.  It
appears to have more magnification in the center and progressivly
less away from the center.  My experience has been with Olympus
stereo microscopes and they all have a flat field.  This effect does
not seem right.  In addition, the effect is noticed throughout the
zoom range and the focus appears to be sharp overall.  Could this be
caused by a maladjustment or incorrect objective lens?

2.  The zoom module consists of a top tube and a bottom tube (split
at the zoom knob) There appears to some flex when a small force is
applied to the top tube.  The gap between the tubes separates several
millimeters at the rear of the tube.  It appears that something
internal is flexing.  I am not sure if this is normal and if it isn't
then how can it be corrected.  This is a concern because the camera
mount increases the stress in this area.

Any help on these issues would be greatly appreciated.

Thanks,

Thank you both for making things clearer for me.  My microscope will
be used mainly for watch work where magnifications in the region of 40
times or less are required.  The following link has an image of a
small watch wheel under magnification using this equiment which may
help demostrate its possibilities.  Click on the MBS-10 link.

Hello Microscopists !

This is an update on my progress.  I was trying to calibrate my
old B&L Research I bench metallograph with a Sony Mavica digital
camera fitted out with an Optem 1.0X video adapter and a Kodak MDS
Universal Adapter, which will reproduce nicely the entire visual
filed seen either through the binocular eyepiece tube or at the
visual port of the metallograph with the binocular viewer removed.

I revisited the Research I's viewing port ... and then I remembered
B&L's advice that one should just use low-magnification eyepieces
in the binocular viewer because the visual magnification is 2.5 times
the photographic magnification.  Oh, oh.  That would place the overall
magnification of a 4 by 5 inch print way beyond the maximum usable
magnification of 1000 times the numerical aperture.  That is, 650X
for a 40X objective, 850X for the B&L's 58X, 0.85 NA objective, etc.

So I abandoned the idea of making a monocular tube for the viewing
port.  Instead, I've been concentrating on the photographic port.
I find that I can make the Kodak MDS 100 digital camera parfocal
with the binocular viewer by using a 5X plain eyepiece or a 5x
hyperplane eyepiece, each with about two inches added to the usual
tube length.  The images come out at the 1000XNA limit, and the
parfocality seems to be maintained with at least two objectives
of widely differing magnification.  It's just the extra-long tube
length that bothers me.  I'll probably go ahead and make a suitable
adapter to hold the MDS 100 and the 5X eyepiece and try the setup
out for a while.  I did find that there is less pincushion distortion
with the low-magnification eyepieces than with higher magnifications.

Another plan would be to obtain a 0.38X video adapter so as to
reduce the image size on the MDS 100's tiny CCD ... with no
eyepiece at all, the magnification ends up way too large ! When I
try a 1.0X video adapter, I also end up with excessive magnification.
However, those video adapters are rather pricey ...

Alan,

The stand the scope is on on that fellows web page costs as much or more
than than the scope. There are a number of used binocular stereoscopes I
would normally choose from over a new one. The fact that a new devices of
any kind takes a large deprecating as soon at leaves dealers show room. No
matter the quality the used price is never more than 2/3 the price new and
50% of new price is very hard to get unless you sell retail to a market than
uses them.

That said, new Lomo microscope are a very good value for the dollar. The
optics are the best bargain there is in new microscopes. They don't make
stereo microscopes that I know of.

The camera attachment does look interesting as appears to attach between the
objective lens and the beam splitter it could use the central axis of the
objective lens and not go though all the many useless surfaces of the stereo
head that erects the image and presents a stereo view.

Taking a picture though all that glass and off axis to boot makes for a
lower contrast image that is stretched as much as the view it was taken
from. If you are just taking pictures for records that is fine. But if image
quality is important a $20 eBay lens with an eyepiece and a tube made to
hold them with the tools shown on the web page will do much better.

Wait and watch on eBay until a 1/3x Nikon video eyepiece comes up. Some work
in a machine shop may be required. I have 2 one I gave $25 bucks for and one
that was a gift. They used to be pretty common when they were selling off
everything after the end of the world in 2000. At least the world as
Silicone Valley knew it. There are a lot more item in the micros ope listing
on eBay but a lot less good stuff.

Mel, I think you probably ran into Panorama Tools in your Helicon
Focus search because of some work that I did ages ago, hacking an
experimental extended depth of field capability into Panorama Tools.
That work is described at
http://www.janrik.net/ptools/ExtendedFocusPano12/index.html .

Trust me, you do not want to use Panorama Tools for extended depth of
field.  Use Helicon Focus or CombineZ5 instead.

However, you may be interested in some of the discussion and tests
described on that ExtendedFocusPano12 page, and I have numerous other
pages on extended depth of field with macro subjects that can be
accessed through
http://www.janrik.net/insects/ExtendedDOF/index.html .

There is also a lengthy discussion thread regarding Helicon Focus and
CombineZ5 at http://www.science-info.org/MGroup/Test_01/P_024.1.htm
and following, and I did some analysis of a particularly troublesome
stack at http://tinyurl.com/dd9ol
(http://www.janrik.net/DOFpostings/DW1/ThoughtsOnExtendedDOFwithDonWil
liamsSequence.html) .

If you actually are interested in panorama photography, then Panorama
Tools is excellent, and I agree with David that PTGui is the place to
start.

--Rik

Dave, Rik
Thanks for the responses.  I have used ImageJ's extended depth of field
function, but I do not know if the results are as good as they can be.  I
downloaded Helicon Focus and will try it out.

Also, at this time I am using Photoshop Elements 4, Panorama function for making
mosaics.  I do not have any experience with any other mosaic making packages and
the Photoshop function is easy to use.  I do not know if it does as good a job
as some other tools, but it does simultaneously stitch horizontally and
vertically.  By taking 4, 6mp photos around a land mark and dumping them into
the Photoshop tool, I can get 20mp results, the 4 lost mp are the overlapped.
areas in the original photos.

Over the years there have been at least two such plugins for ImageJ.

I assume you are referring to the one produced by BIG ?

That is extremely memory hungry and can take longer than forever :-)

At my request, Daniel Sage also provides an alternative version for
download.

Either way, you are better-off with HeliconFocus.

Can you share a picture of one ? eBay sellers often fail to
include essential information in their ads.  I dug up some
images of the Thales-Optem CS38 Standard Video Adapter,for
which I had to download, first, Autodesk's drawing viewer,
which didn't work for the file format used by Thales-Optem,
and then a freeware "Free DWG Viewer" that did open those
files OK, and even let me save them as JPG's before I could
open them with PhotoStudio and print them OK.  Which makes me
wonder about PhotoStudio, which is kinda selective about what
sorts of JPG's it will open ... about which, more below.

In a related matter, this morning I discovered that JPG images
made with my Sony Mavica FD-83 can't be opened with PhotoStudio
2.0 after importing them into WinXP.  Unless I first open them
with Mozilla's jpg viewer and then save them.  And then I was
able to open & edit just a couple of image before PhotoStudio
refused to save the edited images. Yechhh. So I burned 'em into
a CD and opened that with W98.  Now PhotoStudio is happy, but I'm
sure not. Anyone see similar issues with PhotoStudio & WinXP ?

Thanks,

I would like to know where I might purchase zoom
eyepieces for a microscope.

Stephanie

Hi,

Your's is a very unusual request.  I'm not even such such a thing
exists for a microscope.  Most variable magnification devices are
inserted into the light path just above the nose piece that holds the
objectives.  That is where the Zoom mechanism on the B & L DyanZoom is
found.  That is where the Optovar (mag-changer) is located on Zeiss
scopes. That is the scheme for stereo microscopes.

Since most of the advanced microscopes are binocular, a pair of zoom
eyepieces would be unnecessarily expensive and a difficult to adjust
so the images were the same size.

Hello

   dismantled the camera no real problems
  till i got to the very in side lens so decided to
  drill it out with a diamond drill bit (ROLSON)
  DIAMOND BURR set £2.50 (150 Grit)
    had grate difficulty assembling the Chip and what joins to it
    on the shutter and ires bit with the focusing motor
   when done not Happy with it
    (must take more images when taking something apart again!!!!!!!!!!!!!!!!!!!)
   then i had an electric shock and sparks every where
  where must have been still charged
   continued assembling but the camera did not work

I forgot to mention, there is a large capacitor and a somewhat smaller
one, both charged to about 300V for the flash.

You are meant to discharge them and then cover the terminals with
insulating tape.

Could you explain in more detail everything that you did, from start
to finish ?

itemZ7514338892QQcategoryZ71407QQrdZ1QQcmdZViewItem

Can anyone advise if this would be a good purchase for a general purpose hobby
microscope.

Thanks



[Non-text portions of this message have been removed]

Can anyone, please tell me what the difference(s) is between the Zeiss
Cpl and Kpl eyepieces?  Are the Cpl eyepieces less corrected flat-field
and the Kpl more corrected flat-field?  I thought I had read somewhere
that "C" and "K" both indicated "corrected".  Is this perhaps a
difference in manufacter labeling?  Thanks in advance.

Hi, all;

Thanks to everyone who replied to my question about ID-ing
my Zeiss. It is a PM2 (one little meter in the base)
Thanks also for the manual.
Now to do some shopping !!
Tim P (UK)

Aaron is correct.

In addition, since it is the objective lens which carries the Numerical
Aperture (resolution), the zoom eyepiece, if available, would only offer
better resolution up to the limit of the objective N.A. - the rest of the
zoom resulting in "empty magnification".

I suspect the money better spent would be for a higher (or lower) power
objective lens, or auxiliary lens if we are talking about a stereo
microscope.

Good luck, Stephanie.

Gregg

Hello all,

I am looking for a supplier of petrologic slides and glues that will
bond samples for such.  One person on this list sold me some blank
slides, glue sticks, and an Adams petrologic slide box, yet I cannot
find where he got these.

I have spent hours online looking for a supplier of such.

If anyone can help me in this search, please e-mail me off list.

The Zeiss book 'Optical systems for the Microscope' says of their
eyepieces:

"For tubes with an inside diameter of 23.2mm; adapted to a location of
the real intermediate image 10mm below the tube edge; with compensating
effect adapted to the correction of our objectives.
     C-type eyepieces may be used in conjunction with simple types of
objective. Objectives of higher correction should, if possible, always
be combined with Kpl eyepieces. This applies above all to the
Planachromats and Planapochromats".

should try to find a new or used trinocular microscope. If you are not
familiar with what a trinoular microscope is, it has a third port for
a camera. Even if you are not interested in taking pictures now you
probably will be later and I have seen Chinese Trinoculars at this
price. You should check the used microscope market as well.

Also his shipping and handling charge is absurd. I don't like to deal
with people that hide part of the cost in the shipping and "handling"
It cost me like $18 to send my last microscope UPS ground. Now I know
fuel charges are higher but he is a business so he gets a cut rate.

But the main thing is make sure you get a trinocular if you can afford
it and the price you stated is well within the range of import or used
trinocular.

Good Luck,

Frank

Hi,
You can get a good, known brand, used scope on ebay for less money.  This
would include Nikon, Olympus and Leitz.

On 1/1/06, I corrected Microscope to Microscopy in
http://www.couger.com/microscope/links/gclinks.html
http://www.couger.com/microscope/links/gcmag.html

And corrected the same errors in the post to the Yahoo microscope group in
the following text. I deleted the message that had those in error so I don't
send some one on a wild goose chase some day.

*Microscopy Society of America <http://www.microscopy.org/>.
http://www.microscopy.org/ * there is a is a six month embargo after the
date it is published on the magazine before it becomes open access to the
public. Starting with the November 2004 issue the magazine have  high
resolution images with text that can be searched prior to that they appear
to be scanned copies of the magazine. This makes this make Microscopy Today
available to everyone that has an Internet connection no matter were they
are.

Microscopy Today is another publication that is always looking for articles
to print. I have published one or two there. If you are looking for a way to
get exposure to the professional world of microscopy in North America this
is a very good vehicle to use to accomplish that end.  Phil Oshel the editor
of Microscopy Today aggressively seeks material for the magazine and If you
want to work in the field of microscopy Microscopy Today is a good way to
get name recognition. They make every effort to put Modern Microscopy in the
hands of every microscopist in the USA, Canada and Mexico where it is free.
Subscription cost is $50 to the rest of the world. It is trade magazine that
is not a peer reviewed journal that is supported by advertising. As trade
journals go the editors do a very good job making a good magazines that has
good articles and timely information on many subjects not just  the usual
write ups of the advertisers products that you see in many trade magazine.
It fills a niche often overlooked in science today for a place to publish
procedures, methods and other things that don't fit in the classical peer
reviewed journal but still are vitally important to accomplishing the task.
For instance two pages are genially experts from the MSA email
list<http://microscopy.com/MicroscopyListserver/>
http://microscopy.com/MicroscopyListserver/ it is open to all. It is does
not cover very much on light microscopy but it can be a great deal of help
for difficult questions.

Microscopy Today still has a good deal work in it on light Microscopes and
has reticently been purchased by the *Microscopy Society of
America*<http://www.microscopy.org/>it is published every other month,

If anyone whats  Phil Oshel's contact information you can reach him on the
Microscopy Today's web page or I will be glad to send it to by private
email. I just don't want to post it here for the spam harvesting robots to
glean.

Yes, the old literature from Zeiss mention C-eyepiece, KPL
KPL for Korrektur Plan, and certainly CPL is the same, they just
went with the english "correction"

However, browsing in the Zeiss database, I found a big difference in
price.   The CPL eyepiece fixed 10x/18 is listed already from $56.00

The cheapest KPL is over $250.00

Most KPL eyepieces are in metal, many of the CPL are in plastic.

Hi Mel,

Most of us in the USA on this group have chosen older used microscopes made
by Zeiss, Leitz, and AO Spencer. Wild, Reichert, and Olympups have some
followers. In the UK Vickers, Watson and others have more presence and in
the UK and EU Lomo has more presence as well. If only new will do Lomo is
probably the best buy. Be sure you buy Lomo from a factory affiliated dealer
so you get the support and grantee that goes with it gives you a way that
the microscope can be up graded at a late date and assures continuity of of
compatible attachments. There are some good house brands that Fischer,
Brinkmann and others carry but it is very hard to get parts for them at
reasonable prices or really know what you have to order parts.

My thoughts and those of others are collected on a web page for first time
microscope buyers at http://www.couger.com/microscope/links/gcnewbuy.html

Buying an imported Asian microscope on eBay is the about the w
worst possible way I can think of to buy a microscope.

If you have no experience with microscopes buying a used brand name scope
from a local dealer can saves make the difference in a successful experience
and failure due to not being able to figure out how go use your microscope
if something is the least bit out of adjustment. No matter how easy it is to
fix it is very hard to fix if you don't know what is the matter.

Does anyone know about the quality of the Newcon
Yunat 2P3 80-800x educational microscope?

Stephanie

A while back I got a Zeiss Standard outfitted with HD
Epiplans and episcopic illuminator. But the working
distance of the HDs is really small, so I have been
watching eBay hoping that some LD Epiplans would pop
up. Lo and behold, Santa brought some.

But the LD Epiplans have an RMS thread whereas the HD
Epiplans have a 23.9 mm thread. The LD Epiplans also
don't appear to have any means by which the
illumination can be projected to the work.

Did I simply buy the wrong thing? Is there a different
kind of LD that has a 23.9 mm thread and coaxial light
path or is this the only kind of LD there is? How is
it an Epiplan if there is no coaxial light path?

Anyone know how this is supposed to work?
