High Speed Infrared Photoelectric Detector/Photodiode

 

 

1 Imported Binsong Infrared Photodiode

 

2 Diode type：InGaAs

 

 

4 Maximum response frequency：600MHz

 

 

5 Output Voltage Range：0V-12V（The supply voltage is12Vtime）

 

 

6 The output impedance inside the detector is1MOhm，Users need to get the right response speed，Suitable resistors must be combined at the output end.。To maximize the response frequency of the detector，Its output must be connected in parallel.50Ohm-100Ohmic resistance（Generally, it can be connected in parallel.50Ohm terminal，Bandwidth greater than or equal to300MHzThe oscilloscope itself has50Ohmic impedance selection）。The smaller the resistance of output parallel connection，The higher the peak power of the incident optical signal is required.，Otherwise, the lower the output voltage will be.，Users need to find a balance between bandwidth and voltage。generally speaking，Detection pulse width is several hundred nanoseconds、Picosecond or femtosecond laser pulses，The output of the detector needs to be connected in parallel.50Ohm-100Ohmic resistance；If Detector500usreach500nsLaser Pulse，Detector output needs parallel connection1k-10kOhmic resistance；If we detect hundredsms-500usLaser pulse，The output terminal of the detector needs to be connected in parallel.10k-100kOhmic resistance；If the detection is greater than500msOr CW laser，No parallel resistance is required at the output end of the detector.，But if the output voltage is too high，Or to eliminate the effects of natural light.，Appropriate parallel connection100kResistor or potentiometer，One can reduce external noise.，Second, the magnitude of the output voltage can be limited.。

Bandwidth and Response Speed，The Relation between Parallel Resistance and Voltage，You can refer to the English introduction in the picture above.。
