The MKS Instruments/Newport PTS-OPM is a modular optical power meter designed for integration into Model 8800 and 8200 Photonics Test System mainframes. Available in single-channel (PTS-OPM-1) and dual-channel (PTS-OPM-2) configurations, it delivers benchtop-class measurement performance in a compact, stackable format. The module measures optical power across free-space and fiber optic paths from 1 pW to 2 W over the 190 nm to 1800 nm wavelength range, with measurement resolution spanning up to 8 decades depending on detector selection.

– Compatibility & Integration
The PTS-OPM module slots directly into MKS Instruments/Newport Model 8800 and 8200 mainframes. Performance scales with detector selection: silicon detectors cover UV through near-infrared (190–1100 nm), while germanium and InGaAs options extend coverage to 1800 nm. The 818-ADAPT-OPM cable enables legacy 818 Series detector integration without redesign.
