USING INFRARED ILLUMINATOR:
Your night vision monocular is
equipped with two separate built-
in Infrared illuminator lights. The
Infrared light operates in a
spectrum, which is normally
invisible to a naked human eye,
however with the help of the tube,
located inside the unit, you will see a beam of light when
looking though the ocular lens. This Infrared light is here to assist
you in especially dark conditions, where there is not enough
light for the tube to amplify.
The first illuminator (IR1) (see insert image on the top right)
operates on wavelength of 860nm
and provides close-up illumination
while being completely invisible to
the naked eyes and animals (even
if looked directly at the illuminator
lens).
Second illuminator (IR2) (see insert image on the middle right)
operates at a wavelength of 805nm and provides distant
illumination. This illuminator light can be seen if looked directly
at the illuminator lens, however its beam of light is still invisible to
the naked human eye. (NOTE: models with Rangefinder and 5x
lens only feature one illuminator, which operates on 860-940nm
wavelength)
To turn the close-up Infrared
illuminator (14) ON, first make sure
the unit is ON then rotate the
Power Switch (10) to the IR1
position. To do that, you must
gently pull the switch in the
outward direction and then
rotate the switch one dial. When
looking through the ocular lens, you will notice a faint green
(orange on some models) indicator light at approximately 6
o’clock position outside of the field of view – this is to remind
you that the infrared light is on. To turn the infrared light off,
simply rotate the power switch one dial back to ON position.
