JSDopticial Evolution of M7 Lens R&D and Application Scenarios

——Industrialization Journey of Miniature Optical Systems

I. Technology Incubation Period (Early 2010s)

• Core Breakthrough:

First-gen M7 lenses debuted with 2.07mm focal length and 110° FoV, tailored for 1/4-inch sensors , albeit with -6.5% distortion .

• Industrial Pain Point:

Addressed space constraints in early industrial cameras via Φ10×9.4mm ultra-compact size (10.7mm TTL), enabling integration in tight enclosures .

• Key Applications:

Factory Line Inspection: Dimensional checks for small components.

Vehicle Recorder Auxiliary Lens: Wide-angle coverage to eliminate blind spots.

II. Distortion Optimization Era (Mid-2010s)

• Technical Upgrade:

Models like M7-5070-S adopted 5-glass + IR filter architecture, slashing distortion to <-1% (1/4" sensor) while boosting relative illumination >83% .

• Expanded Applications:

Facial Recognition Access Control: 5.7mm focal length with 0.2m minimum focus for precise biometric capture.

Medical Endoscope Assistance: Adapted to Φ2.4mm channels for in-vivo visualization.  

III. Ultra-Wide-Angle Phase (Early 2020s)

• Groundbreaking Product:

M7-1.5mm-S achieved 144° diagonal FoV (1/4" sensor) despite -24% distortion, compensated by F2.0 large aperture for low-light resilience .

• Scenario Innovation:

Panoramic Security Monitoring: Single-lens coverage of corridors + floor areas, replacing dual-lens setups.

Drone Obstacle Avoidance: 120° horizontal FoV enabled real-time 3D modeling within 8m range.

IV. Scenario-Specific Customization (Mid-2020s – Present)

• Technical Diversification:

Product Line Technical Features Target Scenario

Low-Distortion Series Distortion <±2% Facial payment/gate authentication

Wide-Angle Series HFOV >140° Robotic vacuum navigation

Macro Edition MOD=3cm Iris recognition medical devices

• Manufacturing Advancements:

Fully automated production achieved ±0.001mm assembly precision and stability across -20°C~85°C thermal range .

V. Future Trends: AI-Driven Convergence

1. Algorithmic Compensation:

Embedded NPUs for real-time distortion correction, resolving wide-angle/precision trade-offs.

2. Material Revolution:

Titanium lens barrels + liquid lenses enable dynamic focal tuning .

3. Emerging Applications:

AR Eyewear Modules: Replace prism optics with ultra-short-focus M7 lenses.

Bionic Robot Vision: Multi-lens arrays mimicking compound-eye perception.

Through 16 years of evolution, M7 lenses have transformed from industrial components solving basic needs to optical cores defining scenario-specific precision. Their journey proves: Miniaturization isn’t the destination—it’s the launchpad for intelligence.
