M2021測光探測器
The M2021 light detector
M2021測光探測器是由端窗光電倍增管、電源電路和放大電路組成,。光電倍增管輸出的電流信號經(jīng)I-V放大后變?yōu)殡妷狠敵鲂盘枴Ｔ摐y光探測器可以采用電阻調(diào)節(jié)或電壓調(diào)節(jié)兩種方式控制增益,。
M2021 light detector is composed of end window photomultiplier tube, power supply circuit and amplifier circuit. The current signal output by the photomultiplier tube is changed into a voltage output signal after I-V amplification. The gain of the light detector can be controlled by resistance adjustment or voltage adjustment.
