3.26mm Black Light Lens

Product Brief Description

Designed and produced by BOSHI Optical Technology, this high‑performance wide angle lens is developed for imaging hardware equipped with a 1/2.7 sensor. As a 3.26mm fixed focal wide angle lens with F1.0 large aperture, it collects sufficient light under poor lighting surroundings and suppresses motion blur effectively to elevate low‑light imaging results for security monitoring purposes. Adopting M12 mount structure, this wide angle CCTV lens achieves 129.5 degree diagonal field of view to realize extensive scene coverage and minimize monitoring blind zones. Integrated IR cut filter at 650nm supports authentic color presentation during daytime surveillance. Measuring merely 22.5mm in overall length, the unit can be assembled inside compact camera shells for space‑limited installation cases. BOSHI Optical Technology implements rigorous production quality management. The lens keeps steady optical output within temperature ranging from ‑20℃ to 70℃ for indoor and outdoor deployment. It serves as an economical optical option for CCTV systems, indoor monitoring tasks and industrial imaging projects requiring broad field coverage and dependable low‑light performance.

Detailed Product Description

Detailed Parameter

1. Core optical specifications. Developed by BOSHI Optical Technology, this lens matches 1/2.7 sensor. Its effective focal length reaches 3.26mm with tolerance of plus or minus 5 percent. The maximum F number hits F1.0 with tolerance of plus or minus 5 percent, constructing large aperture optical setup to boost light intake capacity. Maximum image circle diameter equals 7.2mm, which fully covers imaging surface of 1/2.7 sensor without vignetting at sensor edges. The optical back focal length registers 4.55mm in air medium, incorporating 0.3mm IR glass and 0.4mm cover glass. Its mechanical back focal length stands at 4.53mm, which perfectly cooperates with standard M12 mount camera assemblies.

2. Field of view and optical distortion. When paired with a 1/2.7 sensor, this wide angle lens delivers 129.5 degree diagonal field of view, 109.4 degree horizontal field of view and 58.2 degree vertical field of view to capture ultra‑wide scenes within small physical dimension. Optical distortion stays below negative 52.6 percent. Such parameter represents reasonable optical compromise to realize broad viewing scope for this wide angle CCTV lens. Chief ray angle is controlled to 11.5 degrees. This specification strengthens compatibility with mainstream image sensors and mitigates image edge shading as well as color deviation.

3. Structure and environmental parameters. Total lens length is 22.5mm with tolerance of plus or minus 0.3mm. Standard M12 mount enables connection with most board camera and compact imaging devices. Lens holder uses PC plus GF material to acquire solid mechanical strength and favorable temperature resistance. Built‑in filter owns 50 percent cut‑off wavelength at 650nm with tolerance of plus or minus 10nm to optimize visible‑light imaging performance for IR cut function. Operating temperature spans from ‑20℃ to 70℃. Storage temperature ranges from ‑40℃ to 85℃ to adapt to diversified climate conditions. BOSHI Optical Technology conducts comprehensive verification on each indicator to guarantee full conformity against original design standards.

Detailed Performance Advantages

1. Superior low‑light imaging performance. The F1.0 large aperture structure enables this 3.26mm fixed focal lens to guide more ambient light onto image sensor chip. It lifts overall image brightness and reduces picture noise under dim circumstances. Comparing against conventional lenses with F1.8 or F2.0 aperture, this unit obtains richer image details under low‑light conditions without additional infrared supplementary lighting. It cuts total system expenditure for complete surveillance hardware.

2. Ultra‑wide viewing scope together with even illumination distribution. This 129.5 degree wide angle lens monitors far larger spatial area compared with ordinary fixed focal optical components. It decreases required camera quantity for single monitoring site and lowers expenditure for equipment purchase and field installation. Relative illumination exceeds 42 percent. Image border area maintains acceptable brightness level without severe dark corner phenomenon. Consistent visual quality is maintained across the full picture frame.

3. Strong reliability and broad equipment compatibility. BOSHI Optical Technology applies robust raw material selection and high‑precision assembly workflows for this wide angle CCTV lens. Stable optical output can be sustained under drastic temperature fluctuation and long‑duration continuous working status. Standard M12 mount supports connection with most security monitoring cameras, industrial imaging lens equipment and embedded imaging modules available in market. Embedded IR cut filter generates lifelike color reproduction for daytime video surveillance and satisfies fundamental operation demands for regular monitoring systems.

4. Miniature dimension and competitive cost efficiency. Overall physical length only reaches 22.5mm. The lens can be embedded inside thin‑profile camera housing and miniature imaging apparatus. It fits hidden installation and sites with limited installation room. Fixed focal mechanical architecture raises finished product yield rate and brings down subsequent maintenance expense. It supplies cost‑competitive optical solution for mass‑oriented surveillance and imaging projects.

Detailed Application Fields

1. Round‑the‑clock security surveillance. This lens tailored for 1/2.7 sensor works well for wide angle CCTV lens deployment in community monitoring, office building surveillance, parking lot observation, retail store security and public zone monitoring. Combined 129.5 degree wide coverage and F1.0 large aperture support non‑stop 24‑hour monitoring. Clear visual output can be generated both under bright daylight and dim night‑time surroundings.

2. Industrial vision and equipment status supervision. BOSHI Optical Technology designs this product to fit general industrial inspection tasks, production line monitoring and automated imaging workflows. Standard M12 mount and steady optical performance match multiple board camera and industrial imaging hardware. It completes machine vision assignments including surface defect checking and facility condition tracking within factory working environment.

3. Imaging function for embedded smart hardware. Compact outline plus wide angle capability make this 3.26mm lens suitable for smart home apparatus, video doorbell equipment and portable action camera products. It supplies large‑range scene capture capacity to support intelligent recognition algorithm and real‑time monitoring operation for consumer‑grade electronic devices.

4. Large‑range indoor monitoring application. For warehouse inspection, building lobby monitoring, elevator surveillance and open indoor area observation scenarios, this wide angle surveillance lens realizes effective large‑area coverage with fewer camera units. Solid environmental adaptability supports long‑term stable running for indoor locations and mild outdoor working conditions.
