| Description | ||||||||||||||||||||||||||||||||||||||
| Photek have developed high resolution magnetic focus intensifiers, which will operate in a proprietary focus coil currently available in 25 and 40mm cathode/screen useable diameter options. While the size and weight of these systems may be a serious disadvantage, the resolution, MFT and image quality is significantly better than MCP based image intensifiers. Tube body construction is metal/ceramic, designed to minimise the use of magnetic materials, which can cause image rotation and geometrical distortion. The tubes can be built with all standard Photek photocathodes and phosphors. With higher efficiency phosphors such as P43, the light gain from a single photoelectron is sufficient to over come the readout noise of a directly coupled 12 bit camera and allows a corresponding 12 bit linear dynamic range. | ||||||||||||||||||||||||||||||||||||||
