High speed diode detector

1 Imported high-speed photoelectric diode

 

2 Wavelength response range：300nm～1100nm

 

3 Detector material is silicon，Probe photosensitive diameter is less0.5mm，The default is free space light to enter the probe.；If the user needs，Can be pasted in front of the probeFCFlange，So that users can directly access the detector with optical fiber。Please explain in advance when purchasing，The default delivery of the detectorFCFlange

 

4 Cut off frequency：>1GHz

 

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

 

 

6 Output voltage range：0-12V（12VVoltage supply）

 

7 The output impedance inside the detector is1MOhms，Users need to get the right response speed，Appropriate resistance must be connected in parallel at the output end.。If the detector wants to maximize the response frequency，Its output must be connected in parallel50Ohms-100Ohm resistance（Generally can be connected in parallel50Ohm terminal，Bandwidth greater than or equal300MHzThe oscilloscope itself also has50Ohm impedance selection）。The smaller the resistance of the output parallel connection，The higher the peak power of the incident light signal is required.，Otherwise, the lower the output voltage，Users need to find a balance between bandwidth and voltage.。Generally speaking，Detection pulse width is several hundred seconds、Second of skin or second laser pulse，The output of the detector needs to be connected in parallel.50Ohms-100Ohms resistance；If the detector500usTo500nsLaser Pulse，Detector output needs to be connected in parallel1k-10kOhm resistance；If you detect hundredsms-500usLaser Pulse，The output of the detector needs to be connected in parallel.10k-100kOhm resistance；If the detection is greater500msOr continuous laser，The output of the detector does not need parallel resistance.，However, if the output voltage is high，Or to eliminate the influence of natural light，Can be properly connected in parallel100kResistance or potentiometer，One can reduce external noise，Second, the amplitude of the output voltage can be limited.。

 

8 Power supply voltage9～24VDC

 

9 Can be used to detect ultra-fast pulse lasers such as second and second，It can also detect nanoseconds laser pulses andusOrmsLevel quasi-continuous laser，Can also be used to directly detect the intensity of continuous laser or non-laser light sources

Shipping List：One photoelectric detector，12VOne DC regulated power supply，For two pieces。
