Why Precision Matters in Optics

In optical systems, even micronlevel deviations can lead to significant performance issues like light scattering, wavefront distortion, or misalignment. Components such as lens housings, mirror mounts, optical benches, and intricate light guides demand not only dimensional accuracy but also exceptional stability and thermal properties. CNC machining, particularly with advanced 5axis mills and ultraprecision lathes, achieves tolerances within ±0.001mm and surface finishes that can reach Ra 0.1 µm or better. This level of precision ensures that lenses and mirrors are perfectly seated and aligned, maintaining the integrity of the optical path.

Material Expertise for Demanding Environments

Optical applications often involve challenging operating conditions. CNC machining is versatile enough to work with a wide range of materials suitable for these environments. This includes:
