An optical power meter (OPM) is a device used to measure the power in an optical signal. The term usually refers to a device for testing average power in fiber optic systems. Other general purpose light power measuring devices are usually called radiometers, photometers, laser power meters, light meters or lux meters.

Anritsu


Anritsu offers the world's most comprehensive range of power meters. The ML2490A series has the performance required for narrow fast rising-edge pulse power measurements (e.g. radar), while the ML2480B series is suited for Wide-band power measurements on signals such as W-CDMA, WLAN, and WiMAX.

Bird Electronic Corporation


5000-XT, Digital Power Meter has been completely redesigned. Ideally suited for field techs and engineers who need to make power measurements anywhere they go, the 5000-XT's new user interface has an intuitive, menu-driven design, making it the easiest to use on the market. It's operable even with one hand and compatible with all our field and legacy sensors.

Keysight Technologies Inc.


Keysight power meters operate with sensors of various types (CW, average and peak and average), covering numerous frequency and power ranges to accurately measure the power of RF and microwave signals. Applications include testing the output power of communication base-station transmitters, cellular telephones, radar system equipment, and much more.

TEGAM Inc.


The Model 1806A Dual Type IV Power Meter is designed for use with thermistor elements and an external DVM to measure high frequency power. It can also function as a standard for the calibration of RF detectors, RF voltmeters, and thermistor mounts manufactured by TEGAM, Weinschel, and Keysight (HP). Thermistor mounts easily interface to the 1806A's front panel binding post connections. Temperature control circuits are included for TEGAM and Weinschel temperature controlled thermistor mounts.
