The LUPHOScan 260/420 HD non-contact 3D optical profilometer delivers the highest accuracy for radius and irregularity on challenging surfaces such as high departure aspheres and freeforms. The industry-leading stability guarantees accuracy even in the most challenging environments and provides fast measurement cycle times with no loss in accuracy. The next generation 3D profilometer/equipment provides an industry first with instrument accuracy better than ±50 nm (3σ) on sample slopes up to 90°.
