The Taylor Hobson Talysurf is arguably the best instrument currently available for measuring aspheres. The DIFFSYS MC2 Option will read-in a Talysurf file (binary or ASCII) and use it to make the final sub-micron corrections to a machined part.

All you do is select the measurement file, and DIFFSYS does the rest. Alternatively, there are several functions to manually manipulate the data, which is displayed graphically : Fold, Flip, Smooth and Offset.

NEW: Multiple files - Any number of successive measurements can be stored and added together, ideal for mold corrections. Hybrid Diffractives - Use a measurement of the base curve to correct the final diffractive cut. 3D - Use one or two 2D measurements to correct a 3D surface. Replicate any surface by importing a raw measurement, and smoothing it.

DIFFSYS can also read-in most types of XZ data from other sources. Send us a sample.
