High Speed Photodiode Detector

1 High Speed Photodiode of Imported Binsong Company

 

2 Wavelength response range：300nm～1100nm

 

3 The detector material is silicon，Sensitive diameter of probe is less than0.5mm，Default Free Space Light Entry Probe；If User Needs，Can be pasted in front of the probeFCflange，So that users can access the detector directly with optical fibers。Please specify in advance when purchasing，The default shipment detector does not carryFCflange

 

4 cut-off frequency：>1GHz

 

5 Rising edge: <300ps，Descending edge: <500ps

 

 

6 Output Voltage Range：0-12V（12VVoltage supply time）

 

7 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.。

 

8 Power supply voltage9～24VDC

 

9 Ultrafast Pulsed Lasers for Femtosecond or Picosecond Detection，It can also detect nanosecond laser pulses andusormsQuasi-CW Laser of Grade，It can also be used to directly detect the intensity of continuous laser or non-laser sources.
