1. Core Parameters & Optical Design Highlights

· Ultra-Wide Field of View (FOV):
Diagonal FOV (DFOV): 147°, Horizontal FOV (HFOV): 120°, Vertical FOV (VFOV): 62.9%. Significantly exceeds conventional wide-angle lenses (e.g., typical DFOV ≈90°), ideal for large-scale surveillance or panoramic capture in confined spaces.

· Distortion Control:
Barrel distortion < -68% (negative value indicates barrel distortion). Despite high nominal distortion, edge deformation is partially corrected via 4 glass elements (4G) with aspherical design, ensuring geometric accuracy in the central region.

· Compactness & Light Efficiency:
Total Track Length (TTL): 20.68mm; F2.6 large aperture enhances low-light performance. Compatible with 1/2.7-inch sensors, enabling low-noise imaging in dark environments.

· Resolution Matching:
Supports 3MP (3-megapixel) sensors, meeting industrial inspection demands for detail recognition (e.g., component size errors <0.1mm).

2. Targeted Industry Applications

· Industrial Automation Inspection:

o Surface Defect Detection: Wide FOV covers conveyor belts, rapidly identifying solder joint voids on PCBs or scratches on plastic parts (precision: ±50μm). The F2.6 aperture minimizes motion blur.

o Precision Dimensional Measurement: Low distortion ensures <1% error in measuring gear tooth pitch or electronic pin spacing, avoiding misjudgment from image stretching.

· Vehicle Surround-View Systems:
147° ultra-wide angle covers vehicle blind spots(e.g., rear/side). Post-distortion-correction enables seamless panoramic stitching.

· Security Surveillance:
Single-lens monitoring of warehouses/workshops reduces multi-camera deployment costs. -30°C to 70°C temperature tolerance suits extreme environments.

· Drone & Robot Navigation:
Lightweight design (typical M12 lens weight <30g) reduces payload power consumption. Wide FOV enhances obstacle-avoidance path planning.

3. Selection & Integration Guidelines

· Sensor Compatibility:
Strictly requires 1/2.7-inch sensors(e.g.,OmniVision OS03B10) to avoid edge vignetting.

· Distortion Correction Mandatory:
Integrate calibration algorithms (e.g.,OpenCV or Halcon) to reduce practical distortion to <5%.

· Mechanical Integration:
For M12 mounts, reserve ≥5mm back-focus distanceto prevent mechanical interference (standard flange distance: 12.5mm)
