Alpha Optics AO-31861 is 18mm, Gen 3, high-gain, high-photosensitivity
Inverting Image Intensifier Tube encapsulated within a hard-surface
insulating sleeve and suitable for passive night vision systems and
goggles. The AO-31861 consists of a high-efficiency (GaAs) extended red
photocathode on a twisted fiber optic output window; glass input window;
micro-channel plate (MCP) current amplifier.
The AO-31861 has a built-in high-voltage power supply with overload
protection circuit which incorporates (ABC) automatic brightness control
to provide constant output image brightness as light levels varies. The
power supply also provides (BSP) bright source protection to guard the
tube against exposure to high levels of light and autogating feature
(optional) to protect the tube against exposure to high levels of light.
The AO-31861 comes in the “Slim” ANVIS format and compatible with
BNVD-15, PVS-14, or MUM-14 type devices. Options with the White Phosphor
screen, autogating power supply and manual gain control are available.
We also offer a model that has been developed specifically for aviation
applications. It has special arrangements that eliminate a possibility
of interaction with cockpit equipment.
