Core Process Advantages for Optical Components
Compared with traditional stamping forming, CNC fine milling and single laser processing, the dual-process collaborative mode fully meets high flatness, low roughness, shadow-free and high dimensional matching processing requirements of precision optical components with stronger process adaptability:
-
Photochemical Etching Process: Adopt low-temperature chemical corrosion integrated forming technology with no mechanical extrusion stress during processing, featuring mirror smooth edge, zero burr, no tool indentation. It applies to processing of 0.01mm-3.0mm ultra-thin optical metal components. No customized mold is required, new product sample delivery can be completed within 3 working days. Uniform etching depth ensures consistent light blocking aperture, low surface roughness avoids stray light reflection, suitable for anti-glare diaphragm and aperture plate mass production.
-
Precision Laser Cutting Process: Equipped with anti-scratch nesting system for cold cutting blanking, ultra-small heat-affected zone, no edge oxidation, no metal discoloration. Irregular light shielding frame, positioning pin hole, concentric aperture and optoelectronic assembly groove can be formed by one-time ultra-precision cutting with machining tolerance controlled within ±0.015mm. Support multi-model flexible production, adapt to optical module iteration, shorten customized optical parts development cycle.
