M7 6.2mm Cone Lens

Product Brief

Manufactured by BOSHI Optical Technology, this dependable 6.2mm fixed focal lens is engineered for large‑scale OEM security projects and optimized for the 1/2.7 inch sensor standard. Featuring F2.6 fixed aperture, this compact miniature optics balances light gathering capacity and usable depth‑of‑field for mid‑range surveillance optics deployments. This professional M7 board lens adopts low chief ray angle lens design kept under 15 degrees and delivers high relative illumination lens performance to improve common defects such as corner vignetting and color shift frequently seen in ordinary mini ip camera component. It offers 74‑degree diagonal field‑of‑view to support object recognition and human‑body identification, and its ample image‑circle tolerance offsets assembly deviation during high‑speed module manufacturing. BOSHI Optical Technology carries out full‑batch optical and mechanical verification for each OEM security board lens, to achieve stable round‑the‑clock imaging for indoor commercial and residential monitoring hardware. Optimized for automated assembly lines, this optical component fits Wi‑Fi cameras, compact IP modules and multiple general‑purpose surveillance devices.

Detailed Product Description

Parameter Analysis

1. 6.2mm fixed focal lens with EFL 6.2±5 percent. This medium fixed focal length is specially calibrated for mid‑range surveillance optics. It will not create severe edge distortion like ultra‑wide optics, nor sacrifice scene coverage the way telephoto compact lenses do. Under conventional wall‑mount monitoring installation height, this focal length supports clear human figure and goods identification within 3‑8 meters observing distance. It works well for entrances, office spaces and retail rooms and avoids performance compromises brought by ultra‑wide or telephoto compact lenses.

2. F2.6 fixed aperture with F/NO 2.6±5 percent. This fixed‑iris specification fits daily surveillance usage scenarios. This F2.6 fixed aperture ensures stable light reception under regular indoor ambient lighting while retaining satisfactory depth‑of‑field. Multiple targets at varying distances within frame can maintain sharpness simultaneously. It avoids out‑of‑focus risks triggered by excessively large aperture of compact miniature optics.

3. 1/2.7 inch format lens optimization. The complete optical system gets simulation and tuning targeting 1/2.7 inch sensor. Its maximum Ø7.0 mm image circle creates sufficient safety margin beyond sensor active working area. When integrating this M7 board lens into camera modules, minor position offset generated by automated SMT equipment cannot cause mechanical vignetting, and effectively raises mass‑production yield for camera OEM customers.

4. Field of view specification with 74 degree Diagonal, 62 degree Horizontal and 33.5 degree Vertical. This angle parameter is calibrated for real security application. 62‑degree horizontal view satisfies most wall‑mount monitoring requirements for offices and retail shops. Its vertical angle adapts standard installation height and prevents pixel resource waste on redundant ceiling or ground image area.

5. low chief ray angle lens with CRA＜15 degree. This represents one key competitive merit of this mini ip camera component. Many low‑cost compact lenses carry high CRA value. When matched with mainstream CMOS sensors, high CRA will produce corner color cast, sensitivity decline and uneven brightness. Controlled below 15 degree, this lens design greatly reduces such optical flaws.

6. Mechanical specs for M7 board lens. TTL reaches 13.42±0.3 mm and BFL reaches 6.5±0.2 mm. Total track length and back focal length follow strict tolerance management. Compact overall dimension enables highly integrated miniature module design. Precise mechanical tolerances deliver consistent optical performance after automated screwing‑in assembly for mass orders of OEM security board lens.

7. Distortion & illumination index. TV Distortion sits at‑12.00 percent and Relative Illumination reaches 58.0 percent. Distortion level is adjusted for video surveillance recording and prevents unnatural scene stretching. 58.0 percent high relative illumination lens performance keeps proper brightness at image corners and lessens ISP algorithm workload for dark edge correction.

Core Performance Advantages by BOSHI Optical Technology

1. The matched design of mature 6.2mm fixed focal lens and F2.6 fixed aperture brings balanced optical performance for mid‑range surveillance optics. The lens maintains stable output under bright daytime condition and dim indoor surroundings. It can fully unlock imaging capability of 1/2.7 inch format lens without heavy dependence on ISP software correction.

2. As compact miniature optics equipped with enlarged 7.0 mm image circle, this M7 board lens provides assembly error tolerance. Slight position deviation during mass module assembly will not form dark image corners and lowers defective product ratio for camera OEM manufacturers.

3. The native feature of low chief ray angle lens cooperates with high relative illumination lens indexes. The product realizes favorable brightness and color consistency from image center toward corners. It efficiently resolves corner shading and color shift issues which trouble many competing mini ip camera component.

4. Mechanical structure gets optimization for automated mass‑production procedures. BOSHI Optical Technology implements sampling inspection covering optical indexes and mechanical dimension for every batch of OEM security board lens. Stable product performance can be guaranteed for large‑volume OEM and ODM surveillance projects.

5. Moderate TV distortion level and edge illumination performance reduce demands for complex image correction algorithm. Cameras assembled with this lens can output natural surveillance video footage and save chip computing resources for other functional modules.

Target Application Scenarios

1. Commercial indoor surveillance equipment. This covers retail anti‑theft cameras, office monitoring modules and lobby corridor compact IP cameras. As mid‑range surveillance optics, this OEM security board lens perfectly matches 1/2.7 inch format lens. Being a qualified mini ip camera component, it captures clear object and human‑body details for medium‑sized public zones.

2. Smart home security devices. Application range contains household Wi‑Fi monitoring cameras and building entrance auxiliary camera modules. Benefiting from compact miniature optics framework and low chief ray angle lens trait, this M7 board lens can adapt home camera hardware with limited internal installation space.

3. Mini embedded vision systems. It supports access‑control auxiliary cameras and small‑size image collection modules adopting M7 interface. The 6.2mm fixed focal lens delivers appropriate magnification for short‑to‑medium‑distance object observation work.

4. High‑volume OEM surveillance camera projects. It applies to mass‑produced analog and IP security cameras. BOSHI Optical Technology supplies cost‑effective optical solution. This F2.6 fixed aperture lens can be embedded into finished camera hardware for global security product brands.
