We will introduce the internal process for dedicated lenses!
Our in-house designers will develop and design custom lenses to meet customer needs, progressing through processes from metal processing to rough grinding, polishing, and core cutting. Lenses that have completed the core cutting process will have a coating applied to their surface to reduce light reflection, followed by inspection, assembly, and adjustment before being turned into products. If you have any questions about the details of the processes, please feel free to contact us. 【Features】 ■ Design: Optical design requests are possible ■ Metal Processing: Cutting of aluminum and brass ■ Rough Grinding: Finishing to the specified shape ■ Polishing: Using high-speed polishing and Oscar-type polishing machines ■ Coating: Conducted via vacuum deposition, etc. *For more details, please refer to our catalog or feel free to contact us.
