SD1329 redefines M12 lens limits with 4G2P hybrid optics + tri-chip compatibility

1. Optical Innovation: 4G2P Enables "One Lens for Multiple Chips"

    Tri-sensor global compatibility: Adapts to 1/2.3", 1/2.5", and 1/2.8" sensors (e.g., OmniVision OS series, Sony IMX317), covering 2MP to 12MP resolutions. Eliminates relensing costs during sensor upgrades. Core breakthrough: curved optimization of dual aspherical plastic lenses (2P):

        4 Glass elements (4G): Suppresses chromatic aberration & spherical distortion, ensuring MTF >0.6@100lp/mm at center.

        2 Aspherical Plastic elements (2P): Precision-molded via thermal compression to correct edge distortion & field curvature, constraining total distortion to <0.58% (vs. industry avg. 3-5%).

Compact optical path & efficiency: TTL 22mm with F2.8 aperture achieves 82° diagonal FoV. Luminous efficiency: 0.25 lm/(mm²·sr), boosting low-light SNR by 18% vs. comparable F2.8 lenses.

2. How <0.58% Distortion Reshapes Machine Vision Precision

    Exponential error compression:
        Actual position error = Calibrated error × (1 + distortion rate)

        Industrial decoding: Low distortion lifts read rates from 92% → 99.5% (lab-tested on reflective metal surfaces).

        Distortion >1% causes >1mm error at 10cm scale; JSD1329’s 0.58% distortion caps error at <0.58mm – meeting semiconductor’s ±0.1mm tolerance demands.

3. Multi-Scenario Validation

    Industrial Automation: High-precision positioning & inspection

        72° horizontal FoV covers 24cm×18cm at 30cm WD; single-frame captures 16 barcodes.

        Global shutter support enables 1.5m/s motion tolerance (+88% vs. standard 0.8m/s lenses).

        56° vertical FoV optimizes robotic cell layout for floor navigation & obstacle avoidance.

    Security & Surveillance: Facial recognition & behavior analysis

        14MP sensor support (e.g., IMX317): 98.3% facial feature recognition at 5m (F2.8 enhances low-light SNR).

        IP67 rating & -30°C to 85°C operating range for harsh environments (e.g., outdoor gates, underground garages).

        UAVs & Medical Devices: Space/accuracy challenges

    Lightweight (Φ14mm) reduces drone payload; 82° wide-angle covers topographic mapping.

    Endoscope guidance: <0.15mm lesion measurement error (FDA Class II compliant).

    Lighting Solutions

        Blue coaxial (450nm): Enhances scratch contrast on metal/glass.

        IR illumination (850nm): Fog-penetrating night vision (requires disabling IR-Cut filter).
