High-Sensitivity Laser Power Sensor with USB Interface The PowerMax-USB UV/VIS Quantum sensors incorporate a Silicon photodiode, for measurement of power from 5 μW to several hundred milliwatts (see chart for maximum power rating at different wavelengths). These sensors work with CW (continuous wave) as well as pulsed sources greater than 100 pps. The standard UV/VIS has a removable nose cone that can be used to reduce stray light, and the Wand UV/VIS incorporates a thin profile metal enclosure to fit into tight locations. Fiber optic accessories are available for use with the Wand UV/VIS sensor. USB sensors plug directly into a PC and can be operated through our PC software application (included) or directly via host commands. FEATURES & BENEFITS

TYPICAL PERFORMANCE DATA We incorporate spectral compensation in the PowerMax-USB UV/VIS sensors to provide accurate measurements across the 325 nm to 1065 nm spectrum. Because the spectral response of the filter and photodiode varies significantly across this wavelength range it is important to check the maximum measureable power at the wavelength of use to make sure the sensor is not being saturated. This curve plots the maximum measurable power, which is the saturation level of the photodiode, as well as the minimum recommended power level, by wavelength.

Like all silicon photodiodes, the UV/VIS Quantum sensor has temperature sensitivity in the infrared region. At 1064 nm, for example, it has a 0.5%/ºC thermal coefficient. Measurement error of up to 2% are present at 1064 nm after a 10 minute warm-up time due to the electronics inside the sensor, and additional error can be present if the ambient measurement environment differs from the calibration wavelength listed on the calibration certificate. In practice, wavelengths shorter than 1000 nm have insignificant effects due to temperature. The following chart references the thermal coefficient at the wavelength of use.
