Auto-gating Image Intensifier is assembled with a high performance tube and gain-adjustable, gated
power supply, using Fiber Optic Faceplate or Anti-veiling Glass(AVG) as the input window and Fiber
Optic Faceplate as output window, with wafer photoelectron system, infrared response extended S25+ photocathode, 6μm electron multiplier MCP, and short &medium decay phosphor P22. Equipped with auto-gating power supply(composed with an oscillater module and a high mutiplier), the intensifier enjoys not only the normal advantages of Gen.2 tube like gain-adjustable, auto-brightness control,reverse polarity protection, low input voltage and current consumption, but also enjoys the benefit of protecting the tube from bright source, fuctioning on gating the cathode voltage to limit incident photo via fast response gate current to meet the various level of luminance.
- Ideal for different illumination environment
- Fast gating，Polarity protection
- Automatic brightness control
- BSP
