Photothermal measuring systems for industrial coating thickness
About OptiSense
OptiSense, founded in 1998 as a spin-off from the Fraunhofer Institute in Germany, specializes in photothermal measuring systems for coating thickness. The company develops and manufactures its "PaintChecker" solutions, which include industrial testing systems and mobile measuring devices, in-house. These products utilize contactless, photothermal technology to measure the thickness of paints, powder coatings, and glazes on various substrates. Key clients are in the automotive, aerospace, medical, and energy sectors.
The company's history includes several milestones, such as developing its first photothermal sensor for a robotic industrial application in 1999 and securing Audi as a pilot customer in 2001. In 2012, OptiSense transitioned from a family-operated startup to a company with a broader management structure to support its international focus, with a presence in Japan, China, South Korea, and the USA. The company is certified according to the EN ISO 9001:2015 quality management system. It has raised a total of $7.44M in funding over four rounds, with the latest being a Series A round in January 2022.
OptiSense's systems are designed to be integrated into industrial processes for quality control and process optimization. The sensors are noted for their miniaturized design, with some models weighing as little as 50 grams. The technology is based on diode lasers and infrared sensors to provide precise, non-destructive measurements on metallic and non-metallic surfaces. The company also offers related services, including consultation, implementation support, calibration, and maintenance.
