Optical Power Meter Reading

Thorlabs expanding line of optical power and energy meters includes power meter consoles a large selection of sensor heads a wireless power meter with a built in photodiode sensor and a fiber optic power meter designed for use in the field.

Optical power meter reading.

An optical power meter is. The optical power meter usually reads in dbm for power measurements or db with respect to a user set reference value for loss. It also helps in determining the power loss incurred to the optical signal while passing through the optical media. The consoles pm100 pm400 and pm300 series when paired with our extensive line of power and energy sensors provide calibrated nist traceable.

When measuring fiber optic power with a power meter attach the meter to the cable. How to use optical power 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. Using a power meter for power measurement.

An optical power meter opm is a testing instrument used to accurately measure the power of fiber optic equipment or the power of an optical signal passed through the fiber cable. Thus a source with a power level of 0 dbm has a power of 1 milliwatt. While most power meters have ranges of 3 to 50 dbm most sources are in the range of 0 to 10 dbm for lasers and 10 to 20 dbm for leds. An optical power meter is the most common type of test equipment used to support fiber optic system.

Turn on the source of power transmitter and view the meter s measurement. Nist developed a testing system to provide absolute power calibrations for optical power meters. The working principle of calibrating an optical power meter. Other general purpose light power measuring devices are usually called radiometers photometers laser power meters can be photodiode sensors or thermopile laser sensors light meters or lux meters.

The term usually refers to a device for testing average power in fiber optic systems. The m in dbm refers to the reference power which is 1 milliwatt. 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. An optical power meter opm is a device used to measure the power in an optical signal.
