In the realm of optical engineering, achieving crystal-clear imaging while minimizing reflections is critical for applications ranging from industrial automation to surveillance systems. M12 lenses with AR coating revolutionize optics, delivering unmatched clarity and rugged durability in one compact design.

TOWIN, a leading supplier of professional optical lenses, has mastered the art of crafting these lenses to meet the demanding needs of modern industries.

M12 Lenses with AR Coating: Technical Specifications Unveiled

M12 lenses, also known as S-mount lenses, are renowned for their compact size and compatibility with PCB cameras. The “M12” designation comes from the 12mm diameter thread (M12x0.5) that allows direct mounting onto printed circuit boards, making them ideal for space-constrained applications. TOWIN’s M12 lenses feature AR coating, a thin layer reducing reflections and boosting light transmission.

Key Parameters of TOWIN’s M12 Lenses with AR Coating

• Focal Length & Distortion Control: TOWIN offers M12 lenses with focal lengths ranging from 2.8mm to 16mm, catering to wide-angle and telephoto requirements. Their low-distortion variants ensure minimal geometric warping, critical for machine vision and 3D scanning.
• Aperture & Light Sensitivity: With apertures up to f/1.4, these lenses excel in low-light environments, capturing detailed images even in dimly lit settings. The AR coating further boosts light transmission by up to 98%, reducing glare and ghosting.
• Coating Technology: TOWIN’s AR coating is engineered using advanced multi-layer deposition techniques, targeting specific wavelengths (e.g., visible, NIR) to optimize performance. This coating also resists scratches, moisture, and chemical exposure, extending the lens’s lifespan.
• Mounting & Compatibility: Designed for seamless integration, these lenses feature an M12 thread and are compatible with cameras supporting resolutions up to 12MP. They align perfectly with TOWIN’s C-Mount and CS-Mount lenses for versatile system design.
• Application-Specific Variants: TOWIN customizes M12 lenses for specialized applications: fisheye for 360° views, pinhole for stealth, and automotive-grade for ADAS.
