The Newport 1935-C is a single-channel optical power meter engineered for precise laser power measurement across ultraviolet through infrared wavelengths. It delivers measurements from 1 pW to 20 kW with ±0.2 dB accuracy and dynamic range spanning -75 dBm to +23 dBm. The instrument accepts Newport detectors with 15-pin D-sub connectors, enabling flexibility across silicon, germanium, InGaAs, thermopile, and pyroelectric detector types. A 5.6″ full-color TFT LCD display provides real-time measurement feedback with ¼ VGA resolution.
