We have several of these Cerium Doped YAP scintillator Plate Seal Detectors in stock. Once our stock is out, we will require approximately 6 weeks lead time and the price will be higher.

This product is a modified 25mm square faced prism from Edmund Optics. A 24mm x 24mm x 1mm YAP:Ce plate was then bonded to one face of the prism using a UV-cured optical adhesive. The last step in the process involves coating several faces of the prism with 50nm of Aluminum.

Why have one side coated with 50 nm Aluminum? First of all, to prevent charging of the scintillator disc by providing a conductive path for the incident electrons. Secondly, the reflective nature of the Aluminum reflects photons generated in the phosphor back to the correct end of your detector. Lastly, the Aluminum keeps stray light from entering your detector.
