About DIFFSYS®

  • What is DIFFSYS®? +


    DIFFSYS® is a Windows® program for the generation of optical surfaces on precision CNC machines, particularily diamond-turning machines.

    It was primarily developed for aspheres, diffractives, fresnels and hybrids, and has now expanded in various directions, to include 3D surfaces (non-circularily symmetric), special tool configurations, and also measurement corrections.

    DIFFSYS® outputs jobfiles in several ASCII formats, compatible with most  commercial machines. The strengths of DIFFSYS® lie in its: 
    • Ease of use & clear graphics
    • Ability to accept design data in many different formats
    • Comprehensive tool corrections, to ensure accurate machining
    • Excellent technical support

    DIFFSYS® was first released in 2000, and has become a market leader, with sales worldwide. It is recognised and recommended by the leading manufacturers of ultra-precision machines.

    Here are some recent additions to DIFFSYS® '3D':


    The red region is a 3D off-axis asphere. The purple region is a transitional blend from the central 3D surface, to the outer '2D' edge segments.




    Slow tool servos: Some surfaces can become very steep or mathematically 'illegal'. You now specify a 'cutoff', at which point DIFFSYS adds a curved corner and a flat at the edge.
