The Labsphere Laser Power Measurement Systems (LPMS) series assures an accurate, reproducible method of determining the total power from a collimated or divergent laser or laser diode. Specifically designed for laser applications, LPMS spheres are ideal for measuring the total power of a beam of optical radiance. Because of the unique geometry of the sphere, beam power measurements are independent of beam polarization, and are insensitive to beam alignment.

The systems provide options for laser power measurement over the 300-to 1800 nm wavelength region for optical powers ranging from 0.1uw to hundreds of watts. The system’s calibrations are traceable to the National Institute of Standards and Technology (NIST).

Each system consists of a laser power measurement sphere, post, post holder and base assembly, a detector assembly, SC 6000 programmable radiometer/photometer and multi-wavelength calibration. A second detector port gives the user the flexibility to add an additional detector assembly for broader spectral sensitivity, or add a spectrometer for spectral characterization.
