Ophir Photonics Announces Low Noise, High Sensitivity Radiometer for Measuring Very Low Powers Down to 300fW

February 17, 2016 San Francisco, CA – Ophir Photonics Group, a Newport Corporation company celebrating 40 years of excellence as the global leader in precision laser measurement equipment, today at SPIE Photonics West 2016 announced the RM9-PD Radiometer, a sensor for measuring the power of very low level CW or quasi CW sources. The RM9-PD integrates a photodiode sensor and an 18Hz chopper into an easy-to-use system that measures very low powers. The sensor is calibrated over the entire range of wavelengths, from 0.2μm to 1.1μm, not just a single wavelength. The sensor features a digitally synthesized lock-in amplifier that reduces external noise to a minimum; this allows the sensor to measure power levels from 300fW to 300nW. The output of the sensor can be displayed on any standard Ophir meter or on a PC or Android smartphone or tablet.
