The 918D Series Photodiode detector is designed to outperform Newport's industry proven 818 Series photodetector family (see Low-Power Photo Detectors, 818 Series), by enhancing their performance with advanced features. The optical detectors feature integrated calibration-data storage, built-in OD1, OD2 or OD3 attenuation filter with electronic position sensing (attenuator On/Off), and temperature sensing electronics for temperature drift compensation, making the detector more accurate in environments with small temperature fluctuations. UV-enhanced silicon, silicon germanium, indium gallium arsenide (InGaAs) detectors are available, covering the wavelength range from 200 to 1800 nm.
As with all other Newport sensor heads, the 918D Series photo detectors include a full spectral response calibration utilizing NIST-traceable standards calibrated with high-precision equipment maintained in Newport’s optical detector metrology facility. Each detector is shipped with its individual calibration data, which is electronically stored inside the detector's EEPROM. A certificate of calibration as well as the actual calibration curves and data are shipped with each detector for attenuator and no-attenuator modes.
Also available are a variety of accessories such as collimating lens assemblies, fiber optic adapters and a 1” optic holder. (see Low Power Photodiode Detector Accessories).
