GENERAL INFORMATION
1.1 Introduction:
This manual provides operation and field level
maintenance instructions for the DTNVS. It also provides
specifications and data on the performance of the
Binocular. To ensure the safety of the operator and the
correct operation of the Binocular it is recommended that
this manual is read carefully in its entirety before any
deployment or field application.
1.2 Equipment Description:
The DTNVS is a self-contained night vision device
that enables improved night vision using ambient
light from the night sky. Typically, 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
DTNVS is equipped with an internal IR LED
enabling the unit to use this to the human eye
invisible light to operate.
