The 918D-ST-IR is a newly redesigned thin-profile, wand detector with a sturdy metal housing. Features include integrated calibration-data storage, built-in OD3 attenuation filter with automatic On/Off detection, and temperature sensing electronics for temperature drift compensation. use the attenuator when measuring the optical power more than 1 mW. Incorporating a large area 10 mm X 10 mm germanium photodiode, this slim optical sensor is ideal for laser and other optical power measurements in tight locations with busy setups. It is supplied with a NIST traced calibration report that details individual detector responsivity measured with and without attenuator. Includes a permanently attached DB15 calibration module. RoHS compliant. See the Related Products tab for the latest compatible power meter models.
