Halogen 100W better of HBO 50W in Fluorescence ?   Message List

Re: Halogen 100W better of HBO 50W in Fluorescence ?

Augusto,

To clarify my comments. First, I am unfamiliar with the particulars of Zeiss
lamphouses. Leica, with which I am somewhat familiar, uses the same lamphouse
for different lamps. Leica's 106 lamphouse, for instance, can come with or
without a mirror and with 2, 4 or 6 lenses, and can accommodate halogen, mercury
or xenon lamps. There is a different mount for each type of lamp. Thus, if
Zeiss is similar to Leica, your lamphouse may not have the proper lenses or
mount. By the way, I would guess that your lamphouse should have a mirror.

Fred
