Dutch United Instruments

Dutch United Instruments (DUI) is a Dutch company based in Delft, the Netherlands. DUI provides optics surface metrology tools for different sizes of optics. Our flagship product is the NMF600 S for optics up to 600mm in diameter. NMF products are based on the proven NANOMEFOS technology by TNO (Netherlands Organisation for Applied Scientific Research). DUI NMF products are specifically designed to provide easy and accurate surface metrology of complex optics to the workshop floor. The fast, non-contact tools are capable of measuring optics ranging from convex to concave and from flat to freeform, with a typical measurement uncertainty below 15 nm RMS. NMF products are based on three basic principles: A cylindrical coordinate measurement machine setup. This giant cd-player setup enables universal measurement of all sorts of optics (small to large, convex to concave), and fast measurement with minimal fast moving axes. A non-contact probe with large range captures the freeform dep...
