Our partner 4D Technology offers a range of state-of-the-art interferometers for measuring the topography and roughness of optical surfaces. Comprehensive, intuitive software solutions enable wavefront analysis and visualization (3D visu, Zernike polynomials, masks, wafer analysis, lens/mirror groups, etc.).
Twyman Green dynamics interferometer (PhaseCam): insensitive to vibrations and particularly well suited to large mirrors and large focal lengths (telescope for example).
Fizeau interferometer (AccuFiz): highly versatile system with wavelengths from 355nm to 10.6µm, cameras up to 6MPx, and low coherence source (SIS) for measurement of closely spaced surfaces.
Dynamic Linnik interferometer (NanoCam): optical surface roughness measurement, insensitive to vibration, robot-mountable.
