The 818-IR/DB has a new attenuator design! The 10 mm clear aperture with the cross hair will improve the detector alignment to the input optical beam more accuray and help avoid detector overfilling.
The 818-IR/DB Germanium (Ge) Photodetector is supplied with a NIST traced calibration report that details individual detector responsivity measured with and without attenuator over the 780 to 1800 nm wavelength range. Exclusive OD3 attenuator technology extends the calibrated optical dynamic range of our photodiode sensor heads by three decades. The serial numbers for the detector and the attenuator are matched to ensure NIST traceability. This model includes a BNC/DB15 calibration module that provides direct compatibility with Newport’s latest power meters, including 1830-R, 1916-R, 843-R, 1918-R and 1936/2936-C/R. The adapter contains the detector calibration data, model number, serial number and calibration date for seamless operation. Also available are a variety of accessories such as collimating lens assemblies, fiber optic adapters, and a bare fiber adapter, and a 1 inch optic holder.
Note that Models 818-IG and 818-IG/CM are available offline0nly.
