This article explains why camera lenses must withstand temperature changes. A lens is both an optical and mechanical system: barrels, spacers, adhesives, and optical elements expand and contract at different rates, shifting element spacing and focus. Even if nothing breaks, the point of best focus can move, softening images in outdoor installations. Optical materials also change refractive properties with temperature. Athermalization—designing the system so thermal changes compensate—addresses this. Applications like automotive, surveillance, drones, and industrial vision face repeated cycling, so testing must verify maintained optical performance, not just power-on survival. The right temperature specification depends on the actual environment, not a universal rating.

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.

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.

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.

This article challenges the assumption that glass lenses are always superior to plastic. Optical-grade polymers offer manufacturing flexibility, lighter weight, and cost advantages for high-volume production. Glass remains valuable for thermal stability and demanding environments. Many modern lenses use both materials for optimal balance. Resolution depends on design, surface accuracy, and assembly—not material alone. Material selection should match the specific camera's requirements, including sensor, environment, volume, and lifetime. Boshi Optics approaches material choice as part of the broader optical design problem, not a simple premium-versus-cheap decision.

Aspherical optics are widely used in modern cameras because they correct spherical aberration and allow designers to achieve high resolution, wide fields of view, and large apertures in compact packages. Unlike spherical surfaces with constant curvature, aspherical surfaces vary gradually from center to edge, improving light convergence and reducing the need for multiple corrective elements. This is especially valuable in smartphones, security cameras, drones, and automotive imaging where space is limited. Manufacturing precision and quality control are critical. Aspherical optics are a design tool, not a guarantee of quality—they work best when properly integrated into the full optical system. Boshi Optics applies them across security, automotive, and industrial applications.
