InGaAsエリアイメージセンサ
G17243-0808T
広い感度波長範囲 (0.9 μm ～ 2.55 μm)、
近赤外2次元イメージセンサ (320 × 256画素)
G17242/G17243-0808Tは、近赤外ハイパースペクトルイメージング用に設計されたInGaAsエリアイメージセンサです。
カットオフ 波長の異なるInGaAsチップを高精度に並列配置して、広い感度波長範囲で高いS/Nを実現しています。CMOS読み出し回路 (ROIC: Readout Integrated Circuit)と裏面入射型InGaAsフォトダイオードのハイブリッド構造を採用しています。1画素は1つのInGaAs フォトダイオードと1つのROICによって構成され、Inバンプにより電気的に接続されています。ROICにはタイミング発生器が内蔵されており、簡単なデジタル入力でアナログビデオ出力が得られます。
■特長
