Newport has introduced the Series 819C/D high power silicon-based integrating sphere detectors, which operate in the ultraviolet and handle up to 10W of optical power. The new CAL2 models feature a built-in temperature sensor and OD1 attenuator sensor. When connected to Newport’s power meter models 1830-R, 1918-R, 1936-R, or 2936-R, they automatically recognise the attenuator On/Off position and the detector head temperature.
Calibrated and traceable to NIST standards, the 819C/D Series spheres operate in wavelengths ranging from the UV region through the visible to the near-infrared (NIR) at 1650nm. The detectors offer superior and accurate measurements with the market’s smallest calibration uncertainty specifications. Available for both diverging (model 819C) and collimated (model 819D) input beams, the line extension to UV and higher-power features make this series an essential tool for critical optical power measurement applications.
There are three sensor materials used in the new integrating spheres series. They include silicon (Si), for detection between 400-1100nm; UV-enhanced Si, optimised for 200-400nm (but calibrated up to 1100nm); and indium gallium arsenide (InGaAs), which operates in the 800-1650nm wavelength range. Available sphere sizes range from 2-in. to 5.3-in. spheres.
