Noyes Power Meter (660/780/850nm)
The Noyes OPM 4-1D optical power meter may be used to measure optical power in all plastic fiber optic applications. When used with an LED or laser light source, the OPM 4 can also measure the attenuation (insertion loss) of any multimode optical fiber. Simple to use, the OPM 4 stores reference settings for each calibration wavelength. An easy to read LCD display shows optical power (dBm or uW) or insertion loss (dB) and the calibration wavelength (nm). The optical input port accepts Noyes thread-on style connector adapter caps. Adapter caps are required and must be ordered separately. The OPM 4 is fully N.I.S.T. traceable and runs on a standard 9-volt alkaline battery.
