Product Overview
Our Image Intensifiers provide the highest performance in terms of resolution, speed of response and in-service reliability to deliver photonic measurements for world-class scientific research.
Photek Image Intensifiers are available in a wide range of sizes and can be supplied with integral high voltage power supplies and ultra-high speed gate units customised to meet the requirements of a specific application.
A range of photocathodes and input window materials enables a wide choice of spectral responses to suit most applications.
The standard fibre optic output ensures a defined output focal plane and allows efficient coupling to CCDs and linear image sensors. A variety of MCP configurations satisfies all gain requirements.
