Holos NT software is available for the measurement of standard geometries and freeform surfaces. The software enables operators to quickly generate a measuring program. The Windows-based measuring software automatically guides the operator and interactively shows the way to mathematical alignment. The basic module, Holos Geo, is used to measure standard geometries; Holos light and Holos Extended are for freeform surfaces. With Holos Digitize, curves and surfaces can be digitized and converted directly to computer-aided design (CAD) data.
