Optical Power Meters

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 market. Our 1936-R/2936-R series boasts state-of-the-art analog boards with a whopping 250 kHz sampling rate and femptowatt level resolution, easily dwarfing competition. The model 1918-R optical power meter is a small portable reader but outperforms many competitors' flagship benchtop instruments. With the addition of Ophir products, our line of optical power meters has expanded to include the Vega and Nova as well as the Ophir virtual power meters. 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 products, Ophir products, and ILX Lightwave products are not 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, and Laser Energy Sensors. 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.
