Si photodiode array
The S12362-021 is a back-illuminated type 16-element photodiode array specifically designed for non-destructive X-ray inspection. The back-illuminated photodiode array is also simple to handle and easily couples to scintillators without having to worry about wire damage because there are no bonding wires and photosensitive areas on the back side.Features
The chip of this product is not sealed and is exposed. Parts such as electrodes on the chip are not protected by an enclosure or window and so require especially strict care during handling compared to ordinary products.
Before using this product, always read “Precautions / Unsealed products” described below.
