DTNVS33 Night vision binocular

DTNVS 33 a self-contained night vision device that enables improved night vision using ambient light from the night sky, the moon, star and/or sky glow. Optically, it is made up of two sets of objective lens, image intensifier and eyepiece lens. 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 and reinverts the image which can then be viewed through the eyepiece lens. In situations where there is no light at all the unit can be switched into the infrared (IR) mode. The DTNVS33 is equipped with an internal IR LED enabling the unit to use this to the human eye invisible light to operate. This allows for a wide range of operators to use the system safely and comfortably.
