フォトンカウンティングヘッド
H7828-01
H7828シリーズは、φ19 mm (3/4")ヘッドオン型光電子増倍管と高速フォトンカウンティング回路、高圧電源回路を内蔵した小型フォトンカウンティングヘッドです。光電子増倍管の高電圧やディスクリミネータの設定はすでに調整してありますので、+5 Vを入力するだけでフォトンカウンティング計測が行えます。小型でも有効受光面サイズはφ15 mmと大きいため効率良く光を集めることができ、また他の光電子増倍管モジュールと比較して耐振動衝撃特性に優れていますので、携帯型装置に適しています。

For modern websites to work according to visitor’s expectations, they need to collect certain basic information about visitors.
