• Generation II—contains a microchannel plate for increased
gain. Generation II devices were designed for more difficult
viewing situations and are mostly used by military or scientific
personnel.
•
Generation III—contains a gallium arsenide photocathode
and a microchannel plate. Generation III devices are
designed for applications such as special military operations
due to their high light sensitivity and clear viewing in the
darkest conditions.
IMAGE INTENSIFIER or INTENSIFIER TUBE—the part of a Famous
Trails night vision system that gathers and increases light to show
a viewable image. See “Generation” for the different image inten-
sifier designs.
INFRARED (IR) ILLUMINATOR—a source of light (such as an
LED display) that outputs in the near-infrared range (750nm to
3um).
LENS SPEED—the ratio of the focal length to the diameter of the
lens. A lower lens speed produces brighter images. (Expressed
as f number.)
MICROCHANNEL PLATE (MCP)—the component located behind
the photocathode that increases gain in Generation II and III
Famous Trails systems by multiplying electrons.
MONOCULAR—a device that contains an image intensifier and
optic set for use with one eye.
MULTIALKALI—a semi conductive substance that coats
Generation I and Generation II photocathodes.
NEAR-INFRARED—the wavelength of light most present at night
and invisible to the human eye. Its range is between 750nm and
3um, the lowest in the infrared category
. For more information,
look up “Photonic Spectrum”.
NOISE—also called video noise or scintillation, it appears as a
slight sparkling within a Famous
T
rails image.
