YAP:Ce Scintillator Disc, 6mm X 0.5mm, 1 side polished, 1 side
This beautifully polished, Cerium Doped YAP scintillator is the last one we have in stock. Although we can obtain others like this, we would require approximately 6 weeks lead time and the price will be higher.
Specify when ordering if you would you like your scintillator coated with 50nm Aluminum on one side?
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.
