Optical Power Meter Guide

Optical power meters and detectors have been served by Newport for over 30 years. The offering ranges from a low cost, hand-held meter to the most advanced dual channel benchtop power meter available in the market. Our 1936-R/2936-R series boasts state-of-the-art analog boards with a whopping 250 kHz sampling rate and femtowatt level resolution, easily dwarfing competition. ILX Lightwave offers and a unique optical power/wavelength meter for accurate optical power measurement with wavelength measurement and a precision fiber optic power meter for test measurement of fiber optic components. Note that Newport and ILX Lightwave products are not cross-compatible.

Selecting an Optical Power and Energy Meter

See our Optical Power Meters to browse our standard models, or select a product series below to learn more about our products and capabilities. We also offer a complete line of Low Power Sensors, Laser Power Sensors, Laser Energy Sensors, and specialty sensors such as the PEPS Series Power & Position Sensors and LIAD Series Lock-in Amplifier Detectors. Power Meter Kits are a good choice for basic power measurements. However, once you have a kit, it is easy to extend the capabilities by purchasing another detector or a meter Newport offers.
