Optical CNC Machining Services
Specialized CNC machining for the optics industry. Our stress-relieved structures and advanced blackout finishes guarantee long-term alignment and crystal-clear imaging performance.
Custom Optical CNC Machining Services
Transform your optical designs into assembly-ready components with our comprehensive turnkey service. We focus on the two critical factors that define optical success: absolute structural stability and superior light path integrity. By managing the entire process—from stress-relieved machining to specialized optical finishing—we eliminate the risks of material deformation and stray light. Simply provide your drawings or requirements; we take care of the high-precision manufacturing and rigorous validation, delivering ready-to-use parts that integrate perfectly into your optical systems.
Advanced Optical CNC Capabilities
Built on a foundation of extreme precision and material expertise. We utilize high-speed 5-axis machining and sub-micron technology to handle the most demanding optical geometries. From specialized polymers to high-grade non-ferrous metals, our core infrastructure is designed to deliver repeatable accuracy for the world’s most sensitive imaging and photonics applications.
High-Stability Structural Machining
Optical components often lose alignment due to microscopic material shifting. To prevent this, we utilize a specialized multi-stage stabilization process that includes deep-cycle stress relieving and precision aging between machining passes. By controlling the material’s internal tension at every step, we produce housings and mounts that remain dimensionally inert. This process ensures that once your lenses are calibrated, the structural integrity of the assembly maintains that alignment permanently, regardless of environmental stress.
Dimensional Stability through Stress-Relief Control
Ensuring permanent alignment by neutralizing material internal stress. Thin-walled optical components are prone to microscopic warping post-machining, which leads to optical axis deviation. We prevent this by integrating a rigorous multi-stage stabilization workflow: combining secondary roughing/finishing passes with precision heat treatments and cryogenic stress-relieving. This capability ensures that every housing and mount remains dimensionally inert, maintaining sub-micron accuracy and perfect lens centering even under extreme thermal cycling from -40°C to +80°C.
Stray Light Management & Surface Mastery
Eliminating ghosting and flare through precision light-path control. To prevent the image degradation caused by internal reflections and tool marks, we offer a dual-approach surface capability. For reflective paths, we achieve a high-precision mirror finish of Ra ≤ 10nm to ensure exact light direction. For non-reflective areas, we execute precision-machined light traps (micro-serrations) and specialized ultra-matte black anodizing. This technical mastery over surface texture ensures all stray light is absorbed at the source, delivering maximum image contrast and purity.

What is Optical CNC Machining?
Optical CNC machining is a high-precision manufacturing process specifically tailored for the support, packaging, or alignment components of optical elements—such as lenses and mirrors. Unlike conventional mechanical machining, this process focuses on achieving exceptionally high geometric accuracy and dimensional stability to ensure the perfect alignment of optical paths. By integrating rigorous tolerance control engineering with specialized stray light control techniques, it provides the structural integrity and thermal performance guarantees required for high-end optomechanical systems.
Advantages of Optical CNC Machining
CNC machining provides unparalleled accuracy for optical systems. It ensures extreme dimensional precision in lens housings and mirror mounts, which is critical for maintaining optical axis alignment and long-term stability.
Optical components often require intricate internal structures. CNC machining easily handles these challenges, producing high-functionality parts like complex lens barrels and multi-axis mounts that are difficult to achieve through other methods.
Our technology works with a wide range of materials, from lightweight alloys to low-expansion metals like Invar. These materials are essential for maintaining focus and structural rigidity during thermal fluctuations.
In the fast-paced photonics industry, CNC machining accelerates the transition from design to product. It allows engineers to quickly test new optomechanical designs and iterate without the cost or delay of fixed tooling.
We deliver exceptional surface finishes and precise textures directly from the machine. This is vital for managing stray light, reducing reflections, and ensuring the perfect fit of precision mechanical interfaces.
