The 818-ST2-UV/DB is a thin-profile, wand detector with a sturdy metal housing. Incorporating a large area 10 mm X 10 mm UV Enhanced Silicon (Si) photodiode, this slim optical sensor is ideal for laser and other optical power measurements in tight locations with busy setups. It even provides a built-in calibrated OD3 attenuator at the flick of a button. The DB15 calibration module is detachable from the BNC connector, allowing interfacing with Newport meters, an oscilloscope, or a current meter as well. The 818-ST-UV/DB photodetector is supplied with a NIST traced calibration report that details individual detector responsivity from 200-1100 nm measured with and without attenuator. Includes a BNC to DB15 calibration module.  For the 3D model, check 918D-ST-UV. 

Note that Models 818-ST2-UV is no longer available, while 818-ST2-UV/CM is available offline only.
