The 818-ST and 818-ST-UV UV/Si detectors put all the performance of the popular 818 Series Si and UV-enhanced Si detector into a narrow-profile, hand-held wand. Incorporating a large 10 mm X 10 mm Si photodiode, these slim detectors are ideal for measurements in tight locations with busy setups. It provides a built-in calibrated OD3 attenuator at the flick of a button. The UV detector is packaged in aluminum housing to avoid burning of plastic housing, resulting in potential damages on optics in the setup, especially in the UV wavelength range. The calibration module is detachable from the BNC connector, allowing interfacing with Newport meters, an oscilloscope, or a current meter as well. For more UV and Si photodiode detector options, see Low-Power Photodetectors, 918D Series, Low-Power Photodetector, 818 Series, and Low-Cost Photodetectors, Entry level 818-xx-L Series. Thermopile (see Thermopile Detectors, 818P Series) and pyro (see Pyroelectric Detector, Energy 818E Series) sensors are also sensitive in UV wavelengths.
All detectors are supplied with a NIST traceable calibration report that details individual detector responsivity measured with and without attenuator. The standard BNC connector allows flexible interfacing with oscilloscopes, lock-in amplifiers or current meters. The model ...

All detectors are supplied with a NIST traceable calibration report that details individual detector responsivity measured with and without attenuator. The standard BNC connector allows flexible interfacing with oscilloscopes, lock-in amplifiers or current meters. The model indicated by the /DB suffix come with an additional BNC/DB15 calibration module that provides direct compatibility with Newport power meters, including 1916-C, 842-PE, 1918-C, 1928-C, and 1936/2936-C. The /CM suffixed models come with an additional BNC/8-pin mini-DIN calibration module that provides compatibility with legacy Newport power meters. In both cases, the /CM and /DB adapters contain also the detector calibration data, model number, serial number and calibration date for seamless operation with the power meter.
