Luna Optics LN-NVM5-HR - Manual (Page 2)

2. Your night vision device operates with batteries. Unlike a daylight
binocular, where you see the image due to light traveling through the glass
and the prisms, the night vision device works by projecting the amplified
image onto a screen. While the tube is the crucial component of any night
vision device, the optical parts of the unit are also very important, as they
gather the light into the tube and bring the projected image to your eye.
Since the image is projected on the screen, just like any TV, it has certain
limited resolution…so please do not expect your night vision device to provide
the same crystal clear image, as you see through your daylight binoculars –
after all, you are using this device in the dark environment, where normally
your vision would be very limited…oh, and another important point – all night
vision devices have green monochrome image – why green? Because human
eye can distinct most details of the viewing image when presented in green
color…other colors do not show you everything…
3. Another very important notice – since your night vision device amplifies
available light hundreds of times – please be sure not to turn the unit on during
daylight or in a well-lit room – the image will be way too bright for your
comfortable viewing and it also may permanently burn the tube inside the unit
and will surely void your warranty. Please note that for the safety of this
device it has lens covers with a little pinhole – to test the unit during daytime
when you bring your newly bought unit home, or in the shop before you buy it.
Please keep these lens covers on during daytime – even if the unit is turned off.
INFRARED ILLUMINATOR
Your night vision monocular is equipped with a built-in Infrared illuminator light
(8). This light operates in a spectrum, which is normally invisible to a 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.

vision, let’s learn how to operate your new device:
