PowerMax-Pro (Coherent Patent #9,059,346) represents a dramatic technological advancement in laser power sensing that combines the broad wavelength sensitivity, dynamic range and laser damage resistance of a thermopile with the response speed of a semiconductor photodiode.
Measurement response times are below 10 μs, as compared to over 1 second for traditional thermopiles. This HP model incorporates a ZnSe diffuser to enable peak power measurements up to 15 kW.
Each PowerMax Pro HP comes with sensor head, cables, software, mounting post with base and users manual. The RS 2k and USB 2k models connect directly to a computer.
The Pro HP with DB-25 connection requires the LabMax Pro SSIM meter, also available for purchase on this page. LabMax Pro SSIM data sheet.
