Precitech Nanoform 250 ultra grind

This 4-axes (X, Z, C, B) diamond turning machine allows form accuracy of less than 0.15 microns PV and surface roughness under 1.5 nm Ra. It can also perform deterministic freeform milling and grinding to a form accuracy of less than 0.20 microns PV and surface roughness under 5 nm Ra. It has a 16-picometer feedback resolution and an operating system with 0.01 nanometer programming resolution and can accommodate optical parts of up to 8-inches diameter and various materials such as metal, glass, plastic and ceramic.

Zeeko IRP 200

This 7-axis CNC optical polishing machine is capable of producing ultra-precise surfaces on a variety of optical materials and surface forms. It can polish convex, concave, freeform and other complex geometries and uses raster, spiral or more complex tool-paths to achieve finishes that can be as good as 2-3 Angstrom.

Talysurf PGI Freeform

Versatile, high-resolution system dedicated to the measurement of spheres, aspheres, diffractive and freeform optics. With a gauge range of up to 28 mm, a resolution of 0.8 nm and the ability to measure slope as steep as 55°, it is ideal for inspection of freeform surfaces, and can compare measurement with various surface equations and representations.

Zygo Verifire

This Fizeau interferometer system provides fast high-precision measurements of plano or spherical surfaces, and transmitted wavefront of optical systems and assemblies. With its 4-inch beam, it can accommodate various material such as glass or plastic, and even precision-machined metal and ceramic surfaces.

Your application requires assembly and testing of complex optical systems? Led by Prof. Simon Thibault, the NSERC Industrial Research Chair in Optical Design is equipped with a clean-room laboratory with centering and testing devices.
