H11903-04はメメタルパッケージ光電子増倍管と高圧電源回路、低雑音アンプを内蔵した光センサモジュールです。アンプにより光電子増倍管の電流出力を電圧出力に変換するため、信号処理が容易です。また、アンプを光電子増倍管の陽極出力ピン近傍に取り付けているため、外来からのノイズの影響を受けにくくなっています。 H11902シリーズよりも広い周波数帯域のDC～200 kHｚをカバーしています。

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.
