FastInterf software

FastInterf software

The processing time of the results is no more than a second.

The interferometer is equipped with FastInterf software, which calculates the following optical surface parameters based on the results of the interferogram analysis:

• surface form error value (N, Defocus Power);
• local (zonal) error value ( ΔN, P-V, irregularity);
• local error RMS;
• Zernike polynomials;
• wedging of transparent plane-parallel windows.

The software has the ability to:

• averaging the results of several interferograms’ processed data;
• subtract the reference wavefront;
• measure the radius of the surface;
• create a file compatible with Zemax for further calculations of the optical system errors;
• display the generated interference pattern on the monitor for visual assessment of the adequacy of the calculation;
• present the result in different forms, including 3D surface topography;
• print out the calculation results in a form convenient for the Customer;
• reverse the wavefront, change the sign;
• substract aberrations up to 3rd order from the measured wavefront.

It is possible to upgrade the software upon Customer’s request.
