The 818-ST2/DB is a newly redesigned thin-profile, wand detector with a sturdy metal housing. Incorporating a large area 10 mm X 10 mm 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/DB photodetector is supplied with a NIST traced calibration report that details individual detector responsivity from 400-1100 nm measured with and without attenuator. Includes a BNC to DB15 calibration module. For the 3D model, check 918D-ST-SL.
Note that Models 818-ST2 and 818-ST2/CM are available offline only.
