Engine Stray Light Zone Notes
Due to high illumination intensity certain objects in the defined stray light zone can reflect light back onto the engine
creating blemishes in the image. Use the following suggestions to eliminate this effect:
•
Increase window size such that stray light can escape the system without reflecting back onto the engine.
See
Example 1
•
Occupy the stray light zone only with black matte surfaces that do not cause strong reflections back onto the
engine. See
Example 2
•
Block light from reaching the stray light zone by placing a matte black optical baffle near the engine such that
only the clear aperture has its light path uninterrupted. See
in Figure 2-11 and Figure
in Figure 2-11 and
2-12.
