SANTA CLARA, Calif., April 30, 2020 — Thermopile SensorsThe PowerMax series of thermopile sensors has been expanded by Coherent Inc. to enable the measurement of laser powers as high as 6 kW.

The PM1K+, PM3K+, and PM6K+ water-cooled thermopile sensors incorporate the novel BB+ broadband coating to deliver reliable power measurements of continuous-wave or modulated lasers up to 1-, 3-, and 6-kW output powers within the spectral range of 190 nm to 11 µm. The ability to sustain high power densities with a 50-mm diameter active area makes these sensors particularly useful for measuring fiber lasers, CO2 lasers, and other high-power industrial laser sources.

Each sensor is available with the DB25, USB, and RS-232 connectors. The DB25 versions are compatible with standalone power meters including LabMax-TOP, LabMax -TO, LabMax-Pro SSIM, FieldMaxII-TOP, FieldMaxII-TO, FieldMaxII-P, and FieldMate, making them a suitable choice for both laboratory use and field service. The USB-equipped models plug directly into a PC, which is most useful in manufacturing, quality assurance, and testing applications, particularly where data logging is required. The RS-232 versions are targeted for embedded OEM integration, since they can plug directly into an industrial system controller.
