Our Optical Housing Machining Services

From complex lens housings to intricate optomechanical assemblies, we deliver precision machining solutions tailored for photonics and optics applications.

CNC Milling

Multi-axis CNC milling for complex optical housings and optomechanical components. Our 3-, 4-, and 5-axis capabilities produce intricate geometries with tight tolerances and consistent, repeatable surface finishes critical to optical alignment.

CNC Turning

High-precision CNC turning for cylindrical lens housings and mounting components. We achieve tolerances down to ±.0002" on challenging materials including titanium, stainless steel, and specialty plastics used in optical systems.

Swiss Turning

Swiss turning for small-diameter, high-precision optical components such as lens mounts and micro-sized housings. Ideal for complex geometries with diameters as small as .010" and exceptional surface finishes demanded by photonics applications.

Optical Prototyping

Production-intent prototyping for optical housings and lens system components. Prototypes are produced on the same machines and inspected with the same equipment as full production parts, enabling seamless scale-up with no reprogramming.

Quality Inspection

Certified quality inspection at every stage of optical housing production. Our OASIS optical inspection system, Global Advantage CMM, and Keyence measuring systems ensure dimensional accuracy and full documentation for every delivery.

Material Expertise

Expert machining of materials commonly specified for optical systems, including titanium, stainless steel, aluminum, PEEK, and specialty alloys — ensuring thermal stability, corrosion resistance, and dimensional integrity in optical assemblies.

No-Failure Quality

Precision Optical Housing Machining That Meets Zero-Failure Standards

Optical systems leave no room for dimensional error — and neither do we. Criterion Precision Machining produces lens housings, lens mounts, and optomechanical components with tolerances as tight as ±.0002", backed by ISO 9001 and ISO 13485 certifications. Our Brook Park, Ohio facility is equipped with multi-axis Swiss turning centers, 5-axis CNC mills, and the OASIS Optical Automatic Smart Inspection System, enabling us to serve photonics manufacturers across the United States with the same uncompromising standards that define our aerospace and medical device work.
