Hi out there,
i am working with a infrared-videomicroscopy setup (Axioskop FS, Zeiss,
Germany; Hamamatsu C5405 ccd-camera) and would like to know if anybody
out there is working with the same setup. When i make experiments with
visible light there is absolute no problem in getting good Nomarski
optics. Switching to infrared illumination leads to stronger noise and
bad visual results although the infrared-filter of the camera has been
removed. Recently I heard of a heat-protection filter between the light
source and the microscope that should be removed because it attenuates
long wavelengths. Because of the possible damage to parts of the
microscope I would like to know wheather anybody out there has removed
this filter and if this caused any trouble.
Thanks in advance
alex
