D-300 is the most versatile night vision system from Night Optics USA can be configured with a variety of image
intensifiers and enhanced with a wide range of optional accessories to meet any
mission requirement. Standard features such as Mil Spec optics, high-power,
multi-stage Infrared Illuminator, and internal low battery and infrared
indicators are packaged in a compact, rugged, weather resistant housing. The
D-300 is the choice of Law Enforcement Professionals and private users who
demand exquisite performance, friendly controls and easy system customization
for different modes of employment.
Included in the D-300G night vision mono goggle package is a fully adjustable, semi-rigged,
padded, commercial headgear allowing scope rotation between eyes, extended eye
relief, and flip-up capabilities.
A large selection of optional accessories make the D-300 extremely versatile.
Detection ranges can be increased by adding to the 1x objective high-resolution
3x or 5x Mil Spec Afocal lenses or replacing it with a 3.6x commercial objective
that can be increased to 7x by coupling with a magnification doubler. To
illuminate distant objects, several external IR Illuminators are available. A
camera/camcorder adaptor attaches the D-300 to 35 mm SLR cameras and camcorders
for nighttime use. Installed on a Mil Spec weapon mount, the D-300 adds night
vision capabilities to daytime holosights like EoTech or Aimpoint. The Night
Optics USA, Inc. proprietary (patent pending) Day/Night Adaptor quickly
transforms a daytime riflescope into a 24-hour system without loss of weapon
zero by allowing quick connection of a D-300 to the eye-piece of daytime optics.
Autogating of image intensifier tubes
consists of automatically regulating voltages to the tube’s microchannel plate
to optimize brightness and protect the tube in significantly changing light
conditions. When it was discovered that the development of filmless image
intensifier tubes (provisionally termed “Gen 4”) was not practical, tube
manufacturers developed very thin-film ion barriers to protect the photocathode
while increasing tube performance.
These thin-film tubes combined with autogated
power supplies provide the current state of the art of image intensification
technology. In 2001 the US Army declared that the term “Gen 4” would no longer
apply to filmless tube technology, resulting in the US military’s current use of
“thin-film, autogated” image intensification tubes as the standard for its night
vision devices. |
