1-15 OPTICAL FUNCTIONS
The optical functions are provided by an objective lens, an image
intensifier, a collimator and two eyepiece lenses (Figure 1-5). The
objective lens collects light reflected from the night scene by the
moon, stars, or night sky, inverts the image and focuses that image
on the image intensifier. The image intensifier converts the
captured light into a visible image, which is then split and
reinverted by the collimator and transmitted to the eyepiece lenses
for viewing.
