裏面入射型構造を採用したＸ線非破壊検査用の8 × 8素子Siフォトダイオードアレイです。裏面入射型フォトダイオードアレイは、入射面側にボンディングワイヤと受光部がないため取り扱いが容易で、ワイヤへのダメージを気にすることなくシンチレータを実装することができます。また製品周囲のデッドスペースが最小になるように設計されており、複数の製品をタイル状に並べて使用することが可能です。なお、チャンネル間のクロストークがありません。

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors. To do this, a site will create small text files which are placed on visitor’s devices (computer or mobile) - these files are known as cookies when you access a website.
