In the world of compact imaging solutions, Fixed Focal Length M12 Lenses stand out as a cornerstone for applications demanding precision, reliability, and cost efficiency. These lenses, also known as S-Mount lenses, are engineered to deliver consistent image quality across industries like industrial automation, security surveillance, and medical diagnostics.

Towin, a leader in optical innovation, offers a range of Fixed Focal Length M12 Lenses tailored to meet stringent performance requirements.

Why Choose Fixed Focal Length M12 Lenses?

Fixed Focal Length M12 Lenses are designed with a non-adjustable focal length, ensuring stable magnification and field of view (FoV) without the need for manual or automatic focusing mechanisms. This simplicity translates to:

• 1. Higher Reliability: No moving parts reduce wear and tear, making them ideal for 24/7 operations.
• 2. Cost Efficiency: Lower production costs compared to zoom lenses, without compromising image clarity.
• 3. Compact Size: Their 12mm thread diameter allows seamless integration into space-constrained devices like embedded cameras and drones.

Towin’s Fixed Focal Length M12 Lens amplify these benefits with advanced optical coatings and precision engineering, making them a top choice for professionals.

• Focal Length: 2.8mm–25mm (e.g., 8mm for mid-range surveillance, 12mm for detailed inspection)
• Aperture (F-number): F1.2–F2.8 (lower values allow more light intake for low-light performance)
• Field of View (FoV): Horizontal: 39°–107° (e.g., 107° HFoV for 2.8mm lens)
• IR Coating: Multi-layer IR coating for optimal color accuracy in day/night applications
• Resolution: Supports up to 8-megapixel sensors
• Material: Glass elements with anti-reflective coatings
• Warranty: 3-year limited warranty

Example Use Cases

• 2.8mm Lens (F1.2, 107° HFoV): Perfect for wide-area surveillance in retail stores or parking lots.
• 8mm Lens (F1.6, 39° HFoV): Ideal for mid-range industrial inspection of assembly lines.
• 12mm Lens (F2.0, 64° HFoV): Used in license plate recognition systems for high-detail capture.

Key Features of Towin’s Fixed Focal Length M12 Lens

1. IR-Optimized Design

Towin’s lenses feature broadband IR coatings that minimize chromatic aberration, ensuring crisp images in both visible and near-infrared spectrums. This is critical for applications like facial recognition or night-vision cameras.

2. Robust Construction

Built with glass optics and metal housing, these lenses resist vibrations and temperature fluctuations, maintaining focus integrity in harsh environments.

3. Cost-Effective Scalability

Towin offers bulk pricing (e.g., packs of 10 lenses), reducing per-unit costs for large-scale deployments like smart city projects.

FAQs

1. What makes Fixed Focal Length M12 Lens better than varifocal lenses?

Fixed lenses eliminate the need for focus adjustment, reducing calibration time and mechanical failure risks. They also offer better low-light performance due to wider apertures (e.g., F1.2 vs. F2.8 in varifocal models).

2. Can Fixed Focal Length M12 Lens be used outdoors?

Yes! Towin’s lenses are weather-sealed and IR-coated, making them suitable for outdoor surveillance. Pair them with IP66-rated cameras for dust and water resistance.
