How do you determine if rod lenses and/or fibers are excessively discolored? What tests are conducted to confirm fitness for use of these components?
The proper transmission of color for rod lenses and fibers is evaluated using visual control and photo analysis. Specifically, the customized IMS target contains different circles representing a color spectrum. Technicians visually compare the actual target colors to the colors as seen through the endoscope. If needed, a photograph of the target as seen through the endoscope is made for comparison to the actual target colors. Any unacceptable discoloration is noted via this visual test.
