Power Detector, Wand-Style, Ge, 780-1800 nm, OD3 Attenuator, DB15

The 818-ST2-IR/DB is a thin-profile, wand IR detector with a sturdy metal housing. Incorporating a large area 10 mm X 10 mm Ge 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. 818-ST2-IR/DB photodetector is supplied with a NIST traced calibration report that details individual detector responsivity from 780–1800 nm measured with and without attenuator. Includes a BNC to DB15 calibration module. For the 3D model of this product, check 918D-ST-IR.
Note that Models 818-ST2-IR and 818-ST2-IR/CM are no longer available.
