A motorized mirror allowed us to choose between wide-field or inclined excitation configurations; a small angle, between 0 and 30°, was typically used to avoid stray-light reflections and reduce background from cell auto-fluorescence.
Additionally, holographic optical systems tend to suffer from stray light due to reflections at glass-air boundaries and multiple interactions with the VHG.
The whole set-up is placed in a light proof black box in order to reduce stray light and secondary reflections that could reach the ICCD sensor at different delays.
But he said the company, famous for caution and self-reflection, strayed when growth, not quality, became its main concern.
b-2 The stray light has the maximum reflections inside the baffle and between the vanes before reaching the optical elements.
The use of such coatings improved image contrast by reducing the stray rays that were produced by reflections in a multiple-component lens.
Meanwhile, stray light caused by total internal reflection on the inner wall of the rod lenses and the objective lens is eliminated.
Stray light (ghost image) may also be due to double reflections on optical surfaces.
· Smell: Kitchen smells, old pizza boxes under the bed, exhaust from cars · Sounds: Critters in the walls, household noises that seem amplified at night · Visions: Reflections in mirrors and windows, bugs · Physical sensations: Breezes, stray fabric.
However in coating the ball lens, stray light was trapped inside the distal end of the endoscope, and upon multiple reflections caused 7x higher autofluorescence of the endoscope coming from the increased fluorescence emission of the epoxy.
