Optical Material Cutting
High-precision laser cutting equipment is employed to accurately cut optical materials (such as glass and crystals) according to design parameters. The flatness error of the cutting surface is controlled within ≤0.01mm, laying a solid foundation for subsequent processing.
Mold Development
Exclusive molds are customized based on product characteristics. Computer simulations are utilized to optimize the mold structure, ensuring its wear resistance and adaptability, providing stable support for rough and fine grinding processes.
Rough Grinding
High-strength abrasive materials are used to rapidly remove excess raw material. The grinding pressure and rotation speed are controlled by a CNC grinding machine, initially reducing the surface roughness to Ra 1.6μm and forming the basic contour.
Fine Grinding
Finer abrasives and polishing pads are applied, and the component surface is processed at the micron level in stages. The curvature error is precisely corrected, achieving a surface roughness of Ra 0.4μm, approaching a mirror finish.
Polishing
Nanometer-level polishing solutions and high-speed polishing equipment are used. Through the synergistic effect of chemical and mechanical actions, surface scratches and subsurface damage are eliminated, ultimately achieving an optical-grade mirror finish with a surface roughness ≤Ra 0.1μm.
Edging
CNC edging machines are used to chamfer and edge the component edges. The dimensional tolerance is controlled within ±0.02mm to prevent stress concentration and improve assembly adaptability.
Coating
Magnetron sputtering or ion-assisted coating techniques are applied to deposit multiple layers of optical films on the component surface. The thickness and refractive index of the film layers are precisely controlled to achieve specific optical properties such as anti-reflection, reflection, and beam splitting.
Bonding
Optical-grade adhesives are used to precisely bond multiple components. The vacuum pressure curing process eliminates air bubbles and stress, ensuring optical uniformity of the bonding surface and enhancing the overall performance of the components.
Inspection → Packaging
Full-parameter testing of finished products is conducted using interferometers, spectrometers, and other equipment, covering indicators such as surface shape accuracy, transmittance, and damage threshold. After passing inspection, anti-static and shock-proof packaging materials are used to ensure that components remain undamaged during transportation and storage.
