Vertical Interferometer System with 750mm Z-Axis

vertical interferometer system


  • precision interferometer tower for production-, quality-, inspection- and metrology lab environments


  • exceptionally large measuring range for radii up to 800mm


  • natural granite column with extremely flat and precise guiding sur-faces provide for ease of use and very acurate measurement of radius if curvature in optical components


  • highly precise and accurate linear scale with exceptional resolution, directly interfaced to fringe analysis software


  • measurement table is balanced and guided on air bearing slide for quick, easy and accurate setup and movement


  • small footprint and exceptional value combined with high accuracy and rigit, maintenance free design


  • robust vibration damping system, perfect for use in industrial pro-duction environments


  • XONOX X-fiz 100 (4") or X-fiz 150 (6") high performance fizeau interferometer with electionical control of zoom, focus and contrast/saturation


  • innovative, powerful and user friendly fringe analysis system X-fringe PS2 with different smart and intelligent modes to suit various applications


  • system can be equipped eiter with PC table, 2 screens, mouse and keyboard or with touch panel for optimized operation and mini-mized space requirement in production environment


  • additionally available in a "tower only" version "B" for integrating existing or 3rd party interferometer units
