Diffsys v4.38

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.
DIFFSYS Purchasing Options

DIFFSYS A Aspheres only

This is the entry-level version for spheres, aspheres, and multi-segment aspheres; with comprehensive diamond tool corrections, lead-in / out codes, sag tables, resize, B-axis, inch/mm, and various jobfile formats. You can add further options later on as required.

DIFFSYS AZ Aspheres + Zones (Diffractives, Fresnels)

Same specification as above, plus diffractives and fresnels. DIFFSYS has become the industry standard for machining zoned surfaces.

DIFFSYS A3 Aspheres + 3D Surfaces

Generates ultra-precision off-axis aspheres, atorics, acylinders, and freeforms, either by raster flycutting or ‘slow/fast-tool-servo’. Lots of features and options. This version also includes the 2D Aspheres-only functions.

DIFFSYS AZ3 Aspheres, Zones, 3D

All of the above.


OPTION MC2 2D Measurement Corrections – including Talysurf

This option (requiring one of the above) allows the user to measure an asphere with a 2D measuring instrument, and feed the data into DIFFSYS to make corrections. It is compatible with Taylor Hobson Talysurf files, and any instrument outputting ZX ASCII data. Multiple-measurements can be added together, and certain limited corrections can be performed on Diffractive/Fresnel and 3D surfaces.

OPTION MC3 3D Measurement Corrections and CAD import

(requires A3 or AZ3) As MC2, PLUS: Will import any 3D XYZ ASCII CAD data or 3D measurement data. Performs a 3D spline smoothing function. Ask for details on the importable formats.

UPGRADE Z : Upgrade ‘A’ or ‘A3’ to include Zones (Diffractives and Fresnels)

UPGRADE 3D : Upgrade ‘A’ or ‘AZ’ to include 3D

UPGRADE MC+ : Upgrade MC2 to MC3

UPDATE UP : A further 12 months Updates & Technical Support
