Intevac Photonics, a subsidiary of EOTECH, is a manufacturer of night vision sensors and devices based in Santa Clara, CA, U.S.A.
History[edit | edit source]
Varian Associates Inc. was founded in 1948. It produced vacuum tubes which could amplify electromagnetic waves at microwave frequencies, and other electromagnetic equipment.[1]
It produced image intensifier tubes for the U.S. military as part of Omni II (and possibly both earlier and later) contracts.
In 1991, the spinoff Intevac, Inc. was founded.[2]
In 2013, the U.S. awarded a contract to deliver Pilot Night Vision Sensors (PNVS) for the Apache helicopter to Intevac Photonics, using their patented EBAPS sensors.[3]
The Intevac Photonics subsidiary was sold to EOTECH in December 2021.[4]
The contract to produce the Modernized Pilot Night Vision Sensor (M-PNVS) was awarded to Intevac Photonics in October 2021.[5]
EBAPS[edit | edit source]
EBAPS, short for Electron Bombarded Active Pixel Sensor, is a registered trademark for a patented technology by Intevac.
EBAPS sensors are digital night vision sensors that surpass the performance of analog image intensifiers.
An EBAPS sensor consists of a GaAs photocathode combined with a CMOS Active Pixel Sensor (APS) using the Electron Bombarded Semiconductor (EBS) gain process, which requires no MCP, achieving extremely low noise.[6]
