6.2mm Cone Lens

Product Brief

Manufactured by BOSHI Optical Technology, this high-reliability 6.2mm fixed focal lens is purpose-built for mass-volume OEM security projects, optimized around the 1/2.7 inch format lens standard. Equipped with F2.6 fixed aperture, this compact miniature optics strikes a fine balance of light‑gathering performance and practical depth‑of‑field for mid‑range surveillance optics deployments. As a professional M7 board lens, it adopts low chief ray angle lens design under 15°, paired with high relative illumination lens performance to mitigate corner vignetting and color shift-a common failure point for low-cost mini ip camera component. It delivers a 74‑degree diagonal field-of-view for recognizable object and human‑body identification, with generous image-circle tolerance to absorb assembly deviation during high‑speed module production. BOSHI Optical Technology conducts full‑batch optical and mechanical validation for every OEM security board lens, ensuring consistent round‑the‑clock imaging in indoor commercial and residential monitoring hardware. Cost‑optimized for automated assembly lines, it serves as a proven optical component for Wi-Fi cameras, compact IP modules and general‑purpose surveillance devices.

Detailed Product Description

Parameter Analysis

- 6.2mm fixed focal lens (EFL 6.2±5%): This medium fixed focal length is calibrated specifically for mid‑range surveillance optics. Not overly wide to trigger heavy edge distortion, nor too narrow to limit scene coverage. For typical wall‑mount monitoring height, this focal length enables clear recognition of human figures and goods within 3‑8m observing distance, ideal for entrances, offices and retail rooms, avoiding the performance trade‑offs of ultra‑wide or telephoto compact lenses.

- F2.6 fixed aperture (F/NO 2.6±5%): Practical fixed‑iris specification for daily surveillance scenarios. This F2.6 fixed aperture delivers stable light intake under normal indoor ambient lighting, while maintaining satisfying depth‑of‑field. Multiple objects at different distances inside the frame can stay sharp simultaneously, eliminating the out‑of‑focus risk caused by over‑large aperture in compact miniature optics.

- 1/2.7 inch format lens optimization: The whole optical system is simulated and tuned for 1/2.7 inch sensor. Ø7.0 mm maximum image circle provides sufficient safety margin beyond sensor active area. When assembling this M7 board lens onto camera modules, minor positional offset from automated SMT equipment will not generate mechanical vignetting, directly lifting mass‑production yield for camera OEM customers.

- Field of view specification: 74° Diagonal / 62° Horizontal /33.5° Vertical. Real‑world security‑oriented angle calibration. The horizontal 62° covers most office and shop wall‑mount monitoring needs, vertical angle fits standard installation height without wasting pixel resources on useless ceiling or ground area.

- low chief ray angle lens (CRA＜15°): One core competitive feature for mini ip camera component. Many budget compact lenses come with high CRA value, which brings corner color cast, sensitivity drop and uneven brightness when matching mainstream CMOS sensors. Controlled below 15°, this design greatly suppresses such optical defects.

- Mechanical specs for M7 board lens: TTL:13.42±0.3 mm; BFL:6.5±0.2 mm. Strict tolerance control on total track length and back focal length. Compact dimension supports highly integrated miniature module design; tight mechanical tolerances guarantee repeatable optical output after automated screwing‑in assembly for OEM security board lens mass orders.

- Distortion & illumination index: TV Distortion‑12.00%, Relative Illumination 58.0%. Application‑tuned distortion for video surveillance recording, without unnatural scene stretching. 58.0% high relative illumination lens performance preserves acceptable brightness on image corners, lowering ISP algorithm burden for correcting dark edges.

Core Performance Advantages by BOSHI Optical Technology

1. The combination of mature 6.2mm fixed focal lens and F2.6 fixed aperture realizes balanced optical capability for mid‑range surveillance optics. It performs steadily under bright daytime and dim indoor environments, fully releasing imaging potential of the 1/2.7 inch format lens without over‑reliance on ISP software correction.

2. As compact miniature optics with oversizing 7.0 mm image circle, this M7 board lens reserves assembly fault tolerance. Minor positioning deviation during mass module assembly will not produce dark corners, cutting defect rate for camera OEM manufacturers.

3. Built‑in low chief ray angle lens property works together with high relative illumination lens metrics. Center‑to‑corner brightness and color consistency are well maintained; it effectively solves corner shading and color drift pain points that trouble numerous competing mini ip camera component.

4. Optimized mechanical dimension for automated mass‑production workflow. BOSHI Optical Technology implements sampling inspection on optical indexes and mechanical dimension for each batch of OEM security board lens. Consistent product performance is guaranteed for large‑volume OEM & ODM surveillance projects.

5. Balanced TV distortion and edge illumination reduce requirement for heavy image correction algorithm. Cameras integrated with this lens can output natural surveillance footage, saving chip computing resource for other functions.

Target Application Scenarios

1. Commercial indoor surveillance equipment: Retail anti‑theft cameras, office monitoring modules, lobby and corridor compact IP cameras. This OEM security board lens, built as mid‑range surveillance optics, matches the 1/2.7 inch format lens perfectly. As qualified mini ip camera component, it delivers clear object and human‑body details for medium‑size public zones.

2. Smart home security devices: Household Wi‑Fi monitoring cameras, building entrance auxiliary camera modules. Thanks to compact miniature optics structure and low chief ray angle lens characteristic, the M7 board lens fits space‑constrained home camera hardware.

3. Mini embedded vision systems: Access‑control auxiliary cameras, small‑size image collection modules adopting M7 interface. The 6.2mm fixed focal lens provides proper magnification for short‑to‑medium‑distance object observation.

4. High‑volume OEM surveillance camera projects: Mass‑produced analog & IP security cameras. BOSHI Optical Technology delivers cost‑effective optical solution, this F2.6 fixed aperture lens can be integrated into finished camera hardware for global security product brands.
