M2021测光探测器
The M2021 light detector
M2021测光探测器是由端窗光电倍增管、电源电路和放大电路组成。光电倍增管输出的电流信号经I-V放大后变为电压输出信号。该测光探测器可以采用电阻调节或电压调节两种方式控制增益。
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.
