Applications
Optical power meters are used in telecommunications, photonics research, and laser system alignment for accurate power measurement and system validation. The Newport 835 serves laboratory and field environments requiring precise measurements in the visible to near-infrared spectrum. Commonly integrated into fiber optic testing setups and laser characterization workflows.
Condition: For Parts or Not Working
This Newport Corporation 835 Optical Power Meter powers on, the dual display lights up, and all front-panel buttons respond. However, we are unable to fully test the unit at our facility — full optical measurement verification would require a compatible detector, which is not included. As a result, this meter is being sold as-is for parts or repair with no functionality guarantee. The power cable is included; no detector is included. Please view our photo set and contact us if you have any questions.
