Chapter 3 Description
Thorlabs' Entry-Level Upright Reflective Confocal Microscope is a complete single-channel system.
By eliminating signals that originate from outside the focal plane, confocal microscopy provides the
ability to acquire high resolution, optically sectioned images from within a thick sample. The CM100
supports reflected-light confocal imaging for viewing the surface structure of biological samples or
for inspection applications.
The CM100 has a 35 mm x 52 mm x 3 mm silver-coated mirror at the front of the scan path that
directs light from the scanners to the objective. In order to use this microscope for widefield as well
as confocal imaging, you can replace this mirror with a beamsplitter. The CM100 is designed to
provide a cost effective entry point to owning a modular confocal microscope that can be upgraded
to an advanced confocal microscope.
