Gentec Electro-Optics (Gentec-EO) is a Quebec, Canada–based manufacturer of measuring and control instruments specializing in laser power and energy measurement for laboratory, hospital, and industrial applications. The company employs between 51 and 200 people and traces a 50-year history in laser measurement to Gentec, Inc., which developed early laser energy measurement products in the 1970s and pioneered thermopile and pyroelectric detectors. In 2000 Gentec Electro-Optics, Inc. was formed from Gentec, Inc. to focus on thermal laser power and energy measurement, and in 2010 Gentec-EO acquired Spectrum Detector Inc., expanding into THz measurement, ultra-sensitive joulemeters, fast pulse-to-pulse energy measurements up to 200 kHz, and Optical TRAP detectors as primary calibration standards. The product portfolio includes the WB series (now W5 and W9) with a high damage threshold above 100 kW/cm2, high-power joulemeters and laser power meters up to 50 kW, and aperture models such as a 145 mm unit capable of measuring up to 385 J, with recent launches including PRONTO-250-FLEX (2024) and PRONTO-250-EZ (2025). Gentec-EO has received industry recognition, including the Steen Award in 2023 for contributions to laser material processing.
