16-element Si photodiode array

S12859-021

null

Back-illuminated photodiode arrays for X-ray non-destructive inspection (element pitch: 1.17 mm)

The S12859-021 is a back-illuminated type 16-element photodiode array specifically designed for non-destructive X-ray inspection. It is modified versions of our previous products (S11212 series: 1.575 mm pitch). The pitch has been changed to 1.17 mm. 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
-Spectral response range: 340 to 1100 nm
-Element size: 0.77 (W) × 2.5 (H) mm/one element
-Element pitch: 1.17 mm (× 16 pixels)
-Mounted on board size: 19.0 (W) × 18.0 (H) mm
-Long and narrow format by multiple arrays
-Supports dual energy imaging (When used in an upper and lower two-layer combination.)

Notice

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.
