Machined optics – custom metallic mirrors

The advantages of machined optics

1. Superior cost-effectiveness for complex geometries

For engineers working with small-to-medium batches or prototyping, machined metal optics offer a significant cost advantage over traditional glass. While glass grinding and polishing are labor-intensive and often require expensive custom tooling for aspheres or off-axis shapes, our deterministic CNC diamond turning requires no upfront tooling costs. By removing the need for multiple specialized polishing stages and reducing lead times, we provide a more economical path from design to finished component – especially for aspheric mirrors and complex freeform optics where glass fabrication costs often become prohibitive.

2. Monolithic design and ‘snap-together’ alignment

Traditional optical assemblies often struggle with complex mounting and manual alignment. With machined optics, we integrate the optical surface and the mechanical mounting datum into a single substrate. Monolithic design can ensure perfect alignment via pins or perforations, reduces assembly time, and increases the ruggedness of the system.

3. Superior structural performance

Unlike glass, metallic mirrors can be ‘lightweighted’ through honeycombing without sacrificing structural integrity. Metals like copper provide rapid thermal equalization, making them the preferred choice for weight-sensitive and thermally volatile environments.

4. Complexity made simple

Our deterministic CNC diamond processing allows for the production of custom aspheric mirrors and complex freeform surfaces that are impossible to achieve via traditional grinding and polishing.
