The RoHs compliant 918D Series Photodiode Sensors are designed to outperform Newport's industry proven 818 Series Low-Power Calibrated Photodiode Sensors, by enhancing their performance with advanced features. These photodetectors feature integrated calibration data storage, built-in OD1, OD2 or OD3 attenuation filter with an electronic attenuator On/Off sensor, and sensing electronics for temperature drift compensation, making the detector more accurate in temperature changes. UV-enhanced silicon, silicon, germanium, and InGaAs detectors are available, covering the wavelength ranges between 200 and 1800 nm.
The 918D Series include a full spectral response calibration utilizing NIST-traceable standards calibrated with high-precision equipment maintained in Newport’s optical detector calibration facility. Each detector is shipped with the 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.
To maintain accuracy and guarantee performance Newport recommends annual photodiode detector calibration. Newport offers many Optical Sensor Calibration Services including the ANSI Z450.3 compliant calibration.
To directly mount the 918D head to an optical table consider the 918D-BASE-KIT. The 918D-BASE-KIT has an optical axis height of 1.00" and is compatible with both Imperial and Metric table tops.
