Optics Manufacturing — Precision Engineering for Custom Optical Components

Explore the complete optics manufacturing process — from CNC machining and optical polishing to coating, assembly, and inspection — for custom optical components.

1. Core Processes in Optics Manufacturing

• CNC Precision Machining
Optical housings, mounts, and fixtures are produced with ultra-precision CNC machining using materials such as aluminum, stainless steel, titanium, and ceramic. Dimensional tolerances can reach ±1 µm, ensuring perfect alignment with optical axes.

• Optical Grinding and Polishing
After machining, optical surfaces are ground and polished to a mirror-like finish (Ra ≤ 0.01 µm). This guarantees light clarity and minimizes scattering.

• Coating Technology
Thin-film coatings such as PVD, IAD, or IBS are applied to improve reflection, transmission, or durability. Anti-reflection coatings reduce glare and increase light efficiency.

• Precision Assembly
Components are assembled in cleanrooms (ISO 5 / Class 100), using laser alignment systems to ensure optical path accuracy and long-term stability.

Commitment to Excellence in Optical Manufacturing

To achieve outstanding image quality, we set uncompromising standards for both materials and manufacturing processes. Our expertise goes far beyond producing individual optical components — we manage the entire production cycle, from raw optical glass to finished lenses, covering all major glass types used in the industry. Each lens and optical element receives specialized coating treatments that deliver the precise optical characteristics required for superior performance.

Our mechanical manufacturing capabilities are equally advanced. To ensure strength and reliability, we use the latest technologies and equipment to produce robust optical filters and housings. With high-end five-axis CNC machining centers, we achieve exceptional precision, flexibility, and repeatability when creating complex geometries and refined contours for lens assemblies. In addition, our in-house electroplating facilities operate under strict environmental controls, allowing us to customize surface coatings to meet specific client needs.

All lens assemblies are performed in dedicated cleanrooms to maintain a contamination-free environment. Experienced technicians carry out meticulous alignment and calibration to meet the most demanding tolerances and optical standards.

Our rigorous testing and quality assurance procedures reflect our commitment to excellence. Every lens undergoes comprehensive testing with advanced instruments such as interferometers and 3D coordinate measuring machines (CMM) to ensure that each component meets the highest accuracy and reliability benchmarks. Certified under ISO 9001, our metrology labs and process controls guarantee consistent, repeatable, and dependable manufacturing that exceeds customer expectations.
