Gen 1 Night Vision May Be All You Need
images can be found under a full moon or urban lighting (some
distortion included). Gen 1 night vision is inexpensive and the most
widely used of all night vision devices.
The gen 1 devices use an
intensifier tube to amplify ambient light by accelerating electrons
that strike a phosphor surface just like a television.
electron leaves the photosensitive photo cathode and one electron
strikes the phosphor
display. The number of
electrons is not multiplied
as they are in the later generations using the MCP disk. This results
in much less amplification and an image with distortion at the edges.
Gen 1 night vision works well with the right IR illuminator and quality
light gathering optics.
intensifier tubes used in gen 1 nvds vary in quality and performance.
in the manufacturing process over recent years are showing up in the
consumer market. Some are better than others. The best ones are hand
picked and find there way into the better of the gen 1 devices.
a quality image intensifier tube with good upfront multicoated glass
optics and an effective IR Illuminator and these devices get the job
What you end up paying for one will depend on:
- -The quality of the image intensifier. Some are better than
up front night vision optics. Good multicoated glass optics that are
optimized for night vision make all the deference in light gathering
- -Weather proofing, water proofing and ruggedness
Illumination is a must with a gen 1. Look for a wide beam at low
magnification and a narrow beam device to make the longer throws.
Many gen 1 units have a small IR illuminator that is always on.
In very low or no light conditions you can pack your own light source,
invisible to the naked eye of man or
