Newport 835 Optical Power Meter is a benchtop instrument that measures laser power over a wavelength range of 400 to 1000 nm. Newport 835 Optical Power Meter provides a measurement range from 2 nW to 2 W in decade steps with resolution down to 0.1 pW. Newport 835 Optical Power Meter includes a dual display with digital readout and analog bar graph, auto attenuator, and selectable time constants.[1][2]
What it is
How it works
The Newport 835 uses an external photodetector (not included with the meter) to convert incident optical power into an electrical signal, which the instrument then processes and displays.[1]
The meter offers selectable time constants (Slow, Med, Fast) and an auto-attenuator feature to manage signal levels across its measurement range.[1]
The instrument includes an IEEE interface for remote control and data transfer, and the operating instructions are printed on the unit itself.[2]
Where it fits in the process flow
General reference — not yet source-verifiedIn manufacturing and research facilities, the meter is employed to verify optical power levels during assembly, alignment, and quality control of optical components and systems.
Applications
Optical power meters are applied in telecommunications, photonics research, and laser system alignment for accurate power measurement and system validation.[1]
The Newport 835 is commonly integrated into fiber-optic testing setups and laser characterization workflows, covering the visible to near-infrared spectrum from 400 nm to 1000 nm.[1]
