I've got a couple of questions about the condenser on my CX31. 1) Using objectives above 10x, I can't focus the condenser. It looks like I need to raise it...
The screw you are describing holds the condenser in the centerable ring. It may be that the condenser is mounted a bit low. Try slightly loosening the screw...
Once you learn how to raise the condenser a bit more, you may find it is still not in focus even though it is touching and raising the slide. This would occur...
Hi Fred, 1) How close to the underside of the slide can the top lens of the condenser be raised? 2) What is the NA of the condenser? Randall ... From:...
Fred: A. Regarding 1) Using objectives above 10x, I can't focus the condenser. It looks like I need to raise it just a bit higher, but there's a stop that...

The "Links" area does already exist on the Group's Home Page. I don't know if a Vendors subdirectory can be created there. From a vendor's POV, a links entry...
Hello John, I'd be in favour of a one off introductory post, followed by an annual reminder. Each type of post should give a general impression of what's...
You're right. I had assumed that because the condenser didn't drop out of the mount when I removed the screw (and the fact that it was described as "fixed" in...
1) The top lens of the condenser is within 1mm (1.5mm at the outside) of the bottom of the slide. The slide is 1mm thick. My coverslips -- which I'm pretty...
I don't think it is a good idea. Soon or later it could lead to abuse, first very subtle then spam like. The forum as it is does cater our needs, should we...
