Newport 818-ST2/DB silicon photodetector wand with a matching DB15 calibration module. Tested, fully functional, and in excellent physical condition.

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.
