Luxel Corporation produces photocathodes for high performance streak cameras, including the Kentech, AXIS Photonique, and Hadland Photonics instruments.
Our photocathodes are ultra-flat for precise time resolution, and extra fresh for generating the strongest signal possible. Photocathodes are built to the customer’s foil thickness specifications and are usually supplied on the customer’s support blanks. Lexan® is preferred as a substrate because it can be made very thin and ultra-flat for less attenuation, and Mylar can be employed if a thicker substrate is required. Luxel photocathodes are commonly produced of 1000Å Lexan coated with 250Å of aluminum for conduction, layered finally with gold, potassium bromide, potassium iodide, or cesium iodide, in a range of thickness from 500Å to 2000Å, depending on the application and user preferences. Gold cathodes can be made without the aluminum coating on ultra-thin Lexan, or in some cases, as freestanding foils.
A new capability for Luxel is the manufacture of low-density cesium iodide photocathodes, which are supplied in a 6µm Mylar / 300Å-500Å aluminum / low-density opaque coating of cesium iodide configuration.
