JPNV is now capable of supplying 25mm image intensifier tubes. Compared with conventional 25mm inverting tube,this new 25mm wafer tube is proximity-focused between the photocathode and MCP, thus significantly smaller in size and lighter in weight. Futhermore, the performance improves to super gen.II level.
The 25mm tubes consists of a S25+ photocathode bonded to AVG input window, a micro channel
plate(MCP), and a fiber-optic phosphor screen with either straight or twister output.
- The larger effective image size
- Straight /Inverting output windows / Concave / Flat-face
- Proximity focused – low distortion
- Flying lead/contact pin connections
- Gain, output brightness adjustable
