Although microscopes more commonly are used with a C-mount adapter, operation with
a detector having an F-mount adapter may also be possible. See Chapter 5, Microscopy
Applications and the adapter literature for further directions.
C-mount
NTE/CCD detectors can be ordered with an integral C-mount adapter. C-mount lenses
simply screw into the front of these detectors. Tighten the lens by hand only. See Chapter
5 for information on connecting to a microscope.
Note:
C-mount detectors are shipped with a dust cover lens installed. Although this lens
is capable of providing surprisingly good images, its throughput is low and the image
quality is not as good as can be obtained with a high-quality detector lens. Users should
replace the dust-cover lens with their own high-quality laboratory lens before making
measurements.
Overexposure Protection
Set the lens to the smallest aperture (highest F-number) and cover the lens with a lens
cap to prevent overexposure.
