Laser power detectors: to 100W in 200ms
With the compact and robust gRAY bare die detectors powers down to 100 uW can easily be measured. With the B01-SMC and the B05-SMC, two common customer concerns were addressed: system integration and temperature monitoring.
The detector is reflow soldered onto a metal core PCB ensuring optimal electrical, mechanical and thermal coupling to this base plate. The PCB can be conveniently mounted onto any heat sink inside the laser system with two screws.
All thermopile detectors have a temperature dependent output signal. The B01-SMC and B05-SMC contain a NTC temperature sensor next to the detector on the PCB to continuously monitor the module temperature if required by the application.
The C100-HW is among the fastest laser power detectors on the market. Powers of up to 100W can be measured with a rise time of only 200 ms for wavelengths ranging from UV to MIR. The output signal is a normalized analog voltage between 0 and 10 V, requiring a supply voltage of 24 V. Water cooling channels are integrated into the housing to keep the sensor temperature constant.
With the B0.5-SC, powers up to 500 mW can be detected on an area of only 2×2 mm2. As with all the other gRAY detectors, the B0.5-SC is sensitive from 190 nm to 15 µm. For easy integration the detector can be reflow soldered like an SMD component. The detector will be available by the end of 2015.
