China 4.8mm image circle Manufacturers, Suppliers, Factory

BOSHI Optics has expanded its manufacturing network with a new factory in Suichuan, Ji'an, Jiangxi—its third facility alongside Shanghai and Shangrao. The Ji'an plant covers 15,450 m² with 200+ staff and an annual capacity of ~9 million lens sets, covering optical cold processing to lens assembly. Combined with existing sites, BOSHI now has ~48,000 m² of manufacturing space and ~20 million pieces monthly capacity. Capabilities span lens barrels, optical components, precision molding, coating, assembly, and MTF testing. The company serves security, automotive, and medical lens applications, offering both standard and custom optical solutions for OEM/ODM projects.

This article clarifies that higher megapixels don't guarantee better image quality—optical resolution, determined by lens performance, MTF, and sensor matching, is what truly matters. Edge sharpness and balanced design are critical, especially for AI vision and security applications. An unsuitable lens can waste sensor resolution, causing blur and recognition errors. Boshi Optics emphasizes real optical performance over megapixel counts, focusing on system-level clarity and reliability for cameras in security, automotive, and industrial uses.

In the world of lens manufacturing, light is our best friend—until it isn't. Whether you are producing lenses for high-end security systems, automotive ADAS, or delicate medical endoscopes, you know the struggle. You design a perfect set of glass elements, only for a rogue beam of light to bounce around inside and create "optical artifacts" that nobody asked for.

BOSHI Optics (Shanghai Silk Optical Technology) is an optical lens manufacturer established in 2016, with roots tracing back over 30 years in China's optical industry. The company has 300+ employees, ~40,000 m² of manufacturing space, 15+ automated assembly lines, and capacity up to 15 million units monthly. It operates three main sites: Shanghai (medical endoscope and precision optics, including 2.4mm outer diameter lenses), Shangrao/Jiangxi (security and surveillance lenses, high-volume manufacturing, 8,500 m² phase one), and Ji'an/Jiangxi (automotive and vehicle-mounted lenses, established 2025, production from 2026, planned 120 million units annually). Capabilities cover optical glass processing, precision tooling, injection molding, lens barrels, coating, assembly, and MTF testing.

In surveillance, resolution is often the headline, but light-gathering capability is what actually delivers a usable image. When the sun goes down, the "spec sheet" battle between an F2.0 and an F1.0 lens becomes very real. If you are looking to upgrade your CCTV system, understanding the interplay between aperture and focal length is the difference between capturing a grainy silhouette and a clear, identifiable face.

The 27th China International Optoelectronic Expo (CIOE 2026) was held from September 9 to 11 at the Shenzhen World Exhibition & Convention Center in Bao'an, bringing together companies, engineers, buyers, and professionals from across the global optoelectronics industry.Boshi Optics participated in the exhibition with a range of optical lens products covering security surveillance, automotive vision, medical imaging, and customized optical solutions.For us, the exhibition was more than an opportunity to display products. It was also a chance to meet customers face to face, understand real-world application requirements, and discuss how optical design and manufacturing can support different imaging systems.As an optical lens manufacturer and optical design solution provider, Boshi Optics combines lens development, manufacturing, and customized optical solutions to support customers from initial requirements through prototype development and production.
