Description
The S13620-02 is an 8 × 8 element Si photodiode array with a back-illuminated type structure for X-ray non-destructive inspection. The back-illuminated photodiode array is easy to handle because there are no bonding wires or photosensitive area on the incident surface side. You can mount a scintillator without being concerned about damaging wires. In addition, it is designed with minimal dead space around the product. This makes it possible to arrange multiple products side by side. There is no crosstalk between channels.
Features
-2D (8 × 8 element) array
-Spectral response range: 400 to 1100 nm
-Package size: 24 (W) × 24 (H) mm
-Element pitch: 3.0 mm × 64 elements
-Easy coupling with a scintillator
Because there are no wires in the photosensitive area and the optical coupling effi ciency with an scintillator can be maximized, it suitable for non-destructive X-ray inspection equipment.
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.
