PM20 model optical power meter

Thorlabs PM20C Fiber Optic Power Meter with InGaAs sensor, 800–1700 nm range, –60 dBm to +13 dBm power measurement, NIST-traceable calibration, and rechargeable handheld design. 1 A PM61CH power meter with a fiber optic patch cable (sold separately) attached to the detector port is shown here. The PM60 and PM61 Series of Fiber Optic Power Meters are robust, full-featured, handheld instruments, which together cover the full range of optical fiber applications. InGaAs (PM20C or PM20CH) or Si (PM20A) Sensors Wavelength Range: 400 nm - 1100 nm (Si) 800 nm - 1700 nm (InGaAs) Power Ranges: -60 dBm to 16 dBm (1 nW - 40 mW) for PM20A -60 dBm to 13 dBm (1 nW - 20 mW) for PM20C -50 dBm to 23 dBm (10 nW - 200 mW) for PM20CH Interchangeable Fiber Connector, FC. The PM20 Series of Fiber Optic Power Meters are robust, full-featured, handheld instruments, which together cover the full range of optical fiber applications within the 400 - 1700 nm range with optical powers ranging from -60 dBm to +23 dBm (1 nW - 200 mW).
