What OptiSense does
OptiSense GmbH & Co. KG, founded around 2000 and headquartered in Haltern am See, Germany, develops and manufactures photothermal measuring systems for non-contact coating thickness measurement under the PaintChecker brand. The company describes itself as the world's leading provider in this niche, with all sensors developed and produced in-house in Germany (made in Germany), enabling custom solutions for unusual applications. The product portfolio is organized into three families: PaintChecker Industrial (automated inline systems with a controller plus multiple miniature sensor form factors: Cube, Tube, Angle, Line and the higher-power Tube-HP) for production-line integration; PaintChecker Mobile (Pen and Gun handheld sensors that are network-independent and eye-safe) for field inspection; and PaintChecker Lab for continuous laboratory testing. Supporting the hardware are PaintChecker OS Manager software for measurement data management and PaintChecker reference/calibration samples, plus a 360-degree lifecycle ServicesSuite covering calibration, training, and support.
OptiSense sells predominantly through a global channel of approximately 30 certified OptiSense Approved Partners spanning Europe (Germany, Italy, France, Netherlands, Belgium, Czech Republic, Poland, Latvia, Turkey), Asia (China, India, Indonesia, Japan, Malaysia, South Korea, Taiwan, Thailand), and the Americas (United States via Rhopoint Americas, Brazil). Its direct enterprise field-sales team (Sales Managers such as Jörg Mülleneisen for Germany) co-sells with channel partners, conducts customer visits in priority markets (notably a documented two-week USA tour in 2025), and delivers technical presentations at major industry events including the European Coating Show (ECS), ACA Coating Tech Conference (Pittsburgh), DSCT Focus Show (Detroit), the Detroit Auto Show, and the JOT Coating and Powder Meeting (Mannheim). Customers span automotive and EV battery manufacturing (a disclosed engagement with BMW Group for battery cell inspection, plus ILB, Metob Group, Giga-Coating), textile technology (Brückner Textile Technologies), lubricants (BECHEM), industrial coaters (WWO across appliances, rail vehicles, and medical technology), and agricultural machinery (Stoz GmbH), among others. Two 2025 product introductions signal R&D momentum: a mini coating thickness testing system for holes, pipes, and hollow parts (presented at JOT 2025 by Dr. Fabian Gaußmann) and a novel photothermal in-motion measurement method for extended surfaces and moving components.
The business model is largely hardware-centric, with revenue streams from industrial systems, mobile devices, lab systems, and reference/calibration samples sold through distributors and supplemented by recurring professional services (calibration, maintenance, training, and technical support) across the equipment lifecycle. Pricing is custom-quoted via distributor or sales representative and structured under multi-year industrial contracts. The company holds DIN EN ISO 9001 quality certification, Q-DAS process quality certification, WEEE registration, and the German Business Award 2023 (Innovation / R&D). It remains privately held as a GmbH & Co. KG controlled by OptiSense Verwaltungs-GmbH, with Managing Directors Joachim Menke and Dr. Jens Heymans; an SEC Form D exempt offering in July 2023 raised $14,425,010 of a $17,100,113 total, supporting ongoing investment in product development and channel expansion.
