2. Product Features
(I) Excellent material
The high-strength and high-toughness metal material is used, which has good deformation resistance and wear resistance. In complex environments and long-term use, it can maintain structural stability, effectively resist external impact and wear, and extend the service life of optical equipment.
(II) Excellent precision
Through advanced processing technology, ultra-high dimensional accuracy and form and position tolerance control are achieved. The inner diameter, outer diameter and the matching size errors of each component are extremely small, ensuring the precise coaxiality of optical components such as lenses after installation, improving the imaging quality of the optical system, and reducing optical errors such as aberrations and chromatic aberrations.
(III) Excellent surface treatment

The black appearance has been professionally surface treated, with excellent anti-rust and anti-corrosion properties, while reducing the surface reflectivity, reducing the interference of stray light on the optical system, optimizing the optical environment, and helping to obtain clear and pure imaging effects.

3. Product Details
From the design and development end, relying on a professional optical accessories design team, we deeply study the principles of optical systems and the adaptation requirements of various equipment, customize the lens barrel structure, and fully consider the optical path planning and component installation convenience. In the processing and manufacturing process, we use CNC precision machining centers, high-precision tools and advanced testing equipment to perform milling, turning, grinding and other processes on metal raw materials, and control the size, finish and other indicators one by one.

In terms of quality inspection, optical measuring instruments, three-coordinate measuring instruments, etc. are used to fully inspect key parameters such as the inner diameter, outer diameter, cylindricity, and coaxiality of the lens barrel to ensure that each product meets high-precision standards. Whether it is used in scientific research-level precision optical instruments to provide a stable carrier for microscopic observation and astronomical observation; or in industrial automation visual inspection systems, it carries lens components to ensure accurate identification and detection on the production line. This black metal lens barrel optical precision parts have excellent performance and reliable quality, becoming a solid foundation for the stable operation of optical equipment, helping various optical application scenarios to achieve efficient and accurate optical operations.
