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