Ceramic type scintillators
Outline
Toshiba has developed high-sensitivity scintillators excellent for use in inspection equipment such as non-destructive testing (NDT) equipment, and medical equipment. Various dimensions/specifications can be met according to customer applications.
Can be matched with the individual elements of photo diode (above 0.4mm)
Min. thickness is 0.2mm (may change according to dimensions and sizes)
Advantages
Can be processed to light receiving element size, with no light scatter between elements.
