What are some manufacturers of small-volume optical power meters

Several manufacturers produce compact or small-volume optical power meters suitable for lab, field, or low-volume applications, including Thorlabs, VIAVI Solutions, Gentec Electro-Optics, and CNI.Notable ManufacturersThorlabs offers a wide range of optical power and energy meters, including fiber optic power meters and wireless photodiode-based devices suitable for field use. Their PM100 series and PM400 console, paired with various sensor heads, provide calibrated measurements across multiple wavelengths and power ranges, making them ideal for small-scale or portable applications (Thorlabs) . VIAVI Solutions produces pocket-sized and low-cost optical power meters designed for installation and maintenance of single-mode and multimode fiber networks. Their SmartClass Fiber MPOLx and OLP series are compact, easy to use, and suitable for small-volume testing or field deployment (VIAVI Solutions) . Gentec Electro-Optics manufactures ultracompact photodiode-based laser power meters capable of measuring microwatt-level powers, alongside thermal detectors for higher power ranges. Their devices are suitable for precise, low-volume measurements in laboratory or research settings (RP Photonics) . CNI (Changchun New Industries) provides thermopile and photoelectric laser power meters with detection ranges from 1 nW to 200 W and broad wavelength coverage, offering flexibility for small-scale optical testing (RP Photonics) . Other Manufacturers include L-com, Novanta Photonics, Agiltron Inc., and O/E LAND INC., which also produce optical power meters suitable for specialized or low-volume applications (Metoree, GoPhotonics) .SummaryFor small-volume or portable optical power meters, the most relevant manufacturers are:Thorlabs – fiber optic and wireless photodiode metersVIAVI Solutions – pocket-sized meters for field and lab useGentec Electro-Optics – ultracompact photodiode and thermal metersCNI – thermopile and photoelectric meters with wide power and wavelength rangesOther options – L-com, Novanta Photonics, Agiltron Inc., O/E LAND INC.
