China 12μm Lens, M22×0.5 Lens Manufacturers, Suppliers, Factory

During the early hardware scouting phase for security, automotive, or robotics projects, I get hit with the same question at least three times a week: "Should we source an F1.0 large-aperture lens for a 'Blacklight' full-color system, or stick to a traditional Infrared (IR) illumination setup?"

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.

In order to effectively carry out heatstroke prevention and cooling work during the high temperature season, enhance the awareness of high temperature labor protection among employees, effectively prevent the occurrence of high temperature heatstroke and various accidents, and safeguard the labor safety and health rights and interests of employees.

A better lens cannot increase a sensor's pixel count or dynamic range, but it can help a cheaper sensor perform closer to its full potential by delivering better contrast, edge sharpness, and light transmission. MTF performance determines how much detail reaches the sensor; a poor lens wastes resolution. A larger aperture improves low-light performance, reducing the need for aggressive processing. The real value lies in system matching—optimizing the lens for the specific sensor and application. This can be a cost-effective strategy, often more impactful than upgrading the sensor alone. Boshi Optics emphasizes application-driven optical design for security, AI, drones, automotive, and medical imaging.

BOSHI Optical Technology visited Maozhai Village in Jiangxi to care for elderly party members, delivering rice and cooking oil. This reflects their commitment to social responsibility alongside optical innovation. Specializing in lenses for security, automotive, and medical use, they believe technology and community care should grow together. They plan more such initiatives.

Looking for the right lens for your security camera? The 4mm fixed lens might be the unsung hero you need. Not too wide, not too narrow—it offers the perfect balance for monitoring stores, offices, entrances, and more. In this guide, we break down how it works, where it shines, its few quirks (like distortion), and why it’s a go-to choice for real-world surveillance—no engineering degree required.
