The 918D Series Photodetector is designed to outperform Newport's industry proven 818 Series photodetector family (see Low-Power Photodetector, 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 photodetectors, the 918D Series 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 Photodiode Detector Accessories).
