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.

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.

Micro-lens arrays: aspheric, any diameter, spacing, and grid size.
