USB-enabled Optical Sensor, Ultra thin Low Power, <1µW NEP, 8 mm aperture

Manufacturer's part number :


Manufacturer Coherent


Description :

The PowerMax-USB Wand UV/VIS Quantum sensors incorporate a Silicon photodiode, for measurement of power from 5 μW to several hundred milliwatts. The measureable power varies significantly by wavelength. Spectrally calibrated filters are used to attenuate the laser beam, thus allowing for a higher average power measurement than is typically possible with a photodiode. They work with CW (continuous wave) as well as pulsed sources greater than 100 pps. The standard Wand UV/VIS incorporates a thin profile to fit into tight locations.
