DUI provides fast, highly accurate, and non-contact NMF surface metrology tools for flat, sphere, asphere, and freeform optics to your workshop floor.

This intuitive workflow based software allows you to setup and perform a measurement in a matter of minutes, calculate and analyze the results and export your data for iterative machining. DUI also offers optional software modules which enable advanced measurement input and analysis of freeform surfaces. For more details, please contact DUI.

Dutch United Instruments (DUI) provides NMF surface metrology tools for different sizes of optics. Based on the proven NANOMEFOS technology by TNO, DUI has developed the NMF platform that is the blueprint for all the NMF products which DUI offers.

2021年3月11日 · 荷兰联合仪器公司 (DUI) 为不同尺寸的光学器件提供 NMF 面形检测工具。 基于荷兰最大的应用科学机构 TNO 所验证的NANOMEFOS 技术，DUI 开发了 NMF 平台，是所有 NMF 产品的蓝图。

The NMF product range currently comprises three sizes: NMF350 S, NMF600 S and NMF800 S. These products are advanced 3D form metrology tools offering the advantages with respect to versatility, accuracy, speed, non-contact and ease of use for measuring any surface form from flat, sphere, asphere to freeform optics.

17 years ago, a few Master and Phd students including the current DUI CTO Rens Henselmans, went on an epic journey to build a dream form metrology machine for optics manufacturing since no one can make what they can’t measure. This dream machine needs to be universal, large, interferometer accuracy, fast, non-contact.
