Customers trust Optimax to create high-quality optics and deliver them fast, and our freeforms are no exception. Designing with freeforms requires fewer elements, lighter weight and increased flexibility for your system.
Freeform optical shapes or optical surfaces are gaining popularity with lens designers and optical system integrators. Now, there are optical fabrication processes that include generation, high speed VIBE polishing, sub-aperture figure correction, surface smoothing and testing of freeform surfaces.
Optimax produces freeform optics from glass, fused silica, crystals and ceramics for UV, Visible and IR applications using proprietary techniques for low scatter surfaces.
Freeforms are optical shapes or optical surfaces that are designed with little to no symmetry. Manufacturing a freeform is similar to that of a highly complex asphere; surface form and local slope change are all factors that influence the complexity of the shape and the manufacturing process used.
Specifying a freeform begins by defining the surface. An optical fabricator needs a clear description of the desired final optic; equation, cloud of points or a 3D model.
Optimax utilizes deterministic CNC machine tools for predictable removal rates and adherence to tight tolerances. To control centration, precision tools maintain the optical axis.

Coatings can make or break an optics performance. Optimax offers integrated coating services to reduce the risk and time delay in coating your optics. Our clean environment thin film coating lab has capability to coat from UV through IR wavelengths. Featuring multiple chambers with deposition sources, including electron-beam and ion assist, Optimax can offer a wide variety of coating options including BBAR, V-coat, and mirror coatings. Custom coatings are also available. Coating verification is supported by Perkin-Elmer spectrophotometers. Coatings Data Sheet.
Optimax inspects 100% of all optics. Test data is provided with prototype orders.
Our metrology must match the sophistication of our manufacturing technology. Optimax offers state-of-the-art metrology, including surface profilers and interferometers to verify that parts meet the form error specification. Testing options are form specific, lenses with mild departure from a best fit sphere have the highest potential for fractional wave precision.
Optimax manufactures a wide variety of optical components. When on-time delivery is crucial, Optimax offers an expedited delivery option with a money back guarantee.
Optimax’s R&D department is continuously looking for ways to improve our fabrication process and produce higher quality optics. Our current research projects are designed to meet future market needs.
