Dutch United Instruments BV

DUI provides NMF surface metrology tools for different sizes of optics. Based on the proven NANOMEFOS technology by TNO, DUI brings the NMF products to the market. NMF platform is specifically designed to provide easy, fast and accurate metrology of complex optics to the workshop floor. NMF is non-contact and capable of measuring optics ranging from convex to concave and from flat to freeform, with a typical measurement uncertainty below well 15 nm RMS.

Specifications of our device:

• Universal and versatile, no setup changes for measuring a broad range of surface shapes such as flat, sphere, asphere and freefrom
• Robust against vibration with closed loop metrology system made of best components available
• Unique non-contact confocal probe with both large NA and axial range, which is capable of measuring freefrom with departure from best-fit asphere up to 5 mm PV and +-5° local slope deviation
• Ease of use with intuitive user interface
• Fast measurement with typical round pieces including freefrom measured in less than 10 mins
• High-density error map and micrometre point spacing line scans, including absolute radius error
• High accuracy with total measurement uncertainty less than 15 nm and repeatability below 1 nm rms
• Product portfolio for various size of optics including NMF350 S, NMF600 S and NMF800 S as well as custom metrology systems

The fast and accurate 3D optical profilometer

DUI BV was established in the Netherlands in 2017 to commercialize TNO’s NANOMEFOS. As a young start-up company, DUI works closely together with technology partners such as TNO and DEMCON. TNO is a Dutch applied scientific research organization with more than 3000 employees. DEMCON has more than 700 highly qualified engineers and is a high-end technology supplier of products and systems, for high-tech, medical, opto-mechatronic and robotic systems. DUI is dedicated to developing ultra-precision asphere & freeform optics metrology instruments. DUI has an experienced and flexible team, which can also provide tailor-made solutions to meet your metrology requirements. We look forward to servicing you with your needs.
