The Netherlands
Dutch United Instruments (DUI), founded in 2017, is a pioneering company based in Delft, the Netherlands. Specializing in optics surface metrology, DUI leverages its flagship product, the NMF600 S, to serve a broad range of optical measuring needs.
Utilizing the advanced NANOMEFOS technology by the Netherlands Organisation for Applied Scientific Research (TNO), DUI offers effective, non-contact metrology tools. Their products cater to diverse optical shapes, from convex to concave and flat, with remarkable precision under 15 nm RMS.
The technology stands on three core principles: a cylindrical coordinate measurement system, a non-contact probe for high-speed data capture, and a separate metrology system with a stabilized HeNe interferometer. These elements ensure accuracy, with repeatability under 1 nm RMS, making it appealing to industries needing precision optics characterization.
Despite no publicly disclosed investments, DUI shows strong technological foundations, making it a prospect of interest for foresighted investors in the optical metrology domain.
