Dutch precision-spectrometer manufacturer, headquartered in Ittervoort, Limburg. Founded 2006 as a spin-out from Philips Heerlen. Produces high-accuracy spectroradiometers, colorimeters, photometers, and 2D imaging colorimeters for inline production environments, primarily for display manufacturing (LCD, OLED, MicroLED, QD-OLED), AV calibration, lighting, biomedical, and analytical applications. CEO Steven Goetstouwers. The company operates its own cleanroom facility and an in-house IBS optical coating machine (acquired 2020), where every filter that ships goes through the same coating line. The closed-loop feedback between each finished device measurement and the next batch's coating recipe is the company's structural differentiator: an embodied, accumulating learning-by-doing process that a coating service bureau does not replicate. Spectral range across standard products is 250 to 1100 nm (UV to NIR).
