英國ET ELECTRON TUBES光電倍增管
英國ET ELECTRON TUBES屬于LUDLUM MEASUREMENTS集團,主要生產光電倍增管及其附屬產品,英國ELECTRON TUBES光電倍增管產品在高溫、低溫環境都能良好地工作,適用于中震蕩、沖擊工況,光通量可達到50M photons/s。光電倍增管PMT是基于外光電效應和二次電子發射效應的電子真空器件,它利用二次電子發射使逸出的光電子倍增,獲得遠高于光電管的靈敏度,能測量微弱的光信號。光電倍增管包括陰極室和由若干打拿極組成的二次發射倍增系統兩部分。電子倍增系統有聚焦型和非聚焦型兩類。聚焦型的打拿極把來自前一級的電子經倍增后聚焦到下一級去,兩極之間可能發生電子束軌跡的交叉。非聚焦型又分為圓環瓦片式(即鼠籠式)、直線瓦片式、拿柵式和百葉窗式。可廣泛應用于光子計數、極微弱光探測、化學發光、生物發光研究、極低能量射線探測、分光光度計、旋光儀、色度計、照度計、塵埃計、濁度計、光密度計、熱釋光量儀、輻射量熱計、掃描電鏡、生化分析儀等儀器設備中。
