Short Description

Labsphere′s LPMS laser power meters measure the CW output power of lasers in the range 15 µW to kW in the spectral range from 300 nm to 20 µm. The unique arrangement of the integrating sphere and the detector inputs enable the measurement of laser sources with a beam divergence of up to +/- 40°. At the same time, the measurement is not influenced by changes in the beam coupling. The LPMS system consists of LPM integrating spheres with diameters of 2, 4 and 6 inches, a detector, readout electronics and a power calibration. A second detector input can be used for an optional spectrometer. Various detectors such as silicon, InGaAs or germanium are available. With three different coatings of the integrating sphere (Spectraflect®, Spectralon® and InfraGold®), a wide spectral range is covered. Cooled gold-coated integrating spheres are available for measuring high-power lasers.
