The 918D-ST-UV is a wand-style photodiode sensor with a 10 mm × 10 mm UV-enhanced silicon active area, designed for optical power measurements from 200 to 1100 nm. It features a built-in OD3 attenuator with automatic position detection and temperature compensation for use with Newport power meters. The sensor is housed in a rugged anodized aluminum case and includes a permanently attached DB15 calibration module containing detector calibration data. It has a maximum measurable power of 2 W, a noise equivalent power of 0.018 W/√Hz, and calibration uncertainties of 4% at 200-219 nm, 2% at 220-349 nm, 1% at 350-949 nm, and 4% at 950-1100 nm without the attenuator. Uniformity is ±2% and linearity is ±0.5%.
The 918D-ST-UV 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. 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 is supplied with a NIST traced calibration report that details individual detector responsivity measured with and without attenuator. The DB15 calibration module provides direct compatibility with Newport’s latest power meters (see Compatible product list below).
