G11475～G11478シリーズは、近赤外マルチチャンネル分光測光用に設計されたInGaAsリニアイメージセンサです。こ れらのリニアイメージセンサは、InGaAsフォトダイオードアレイとCMOSチップ上に形成されたチャージアンプ、オフセット補償回路、シフトレジスタ、およびタイミング発生回路で構成されています。チャージアンプはCMOSトランジスタアレイで構成され、 InGaAsフォトダイオードアレイの各画素に接続されています。各画素からの信号は電荷蓄積モードで読み出されるため、近赤外域で高い感度と安定した動作が得られます。従来品に比べてデータレートが上がり、高ゲイン時のリニアリティ特性も向上してい ます。パッケージは気密封止されており信頼性に優れています。 CMOSチップ上の信号処理回路は、外部電圧によって2種類の変換効率 (CE: conversion efficiency)から選択できます。

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.
