Wide Angle Lens – S01514013720F

S01514013720F is 1.5mm Ultra-wide-angle lens with Built-In Filter, F2.0 Low F-number M12/S-Mount Lens, 1/4″ VGA resolution Fixed iris CCTV lens.

1.5mm M12 Ultra Wide Angle Lens for Compact Vision Systems

This 1.5mm M12 ultra wide angle lens is designed for compact imaging systems requiring an extremely broad field of view within a 1/4-inch image format. With a 169° diagonal FOV, 137° horizontal FOV, and 112° vertical FOV, the lens captures a wide scene from a very short focal length. Its F2.0 fixed aperture, manual focus, 0.2m minimum object distance, and compact 2G2P+IRCF optical structure make it suitable for embedded cameras, compact monitoring systems, automotive vision, and space-constrained imaging equipment.

For engineers selecting a compact lens, the combination of focal length, sensor size, field of view, and distortion should be evaluated together. TOWIN’s Lens Selection Guide provides additional information on selecting the appropriate optical configuration for different imaging requirements.

M12 Ultra Wide Angle Lens Core Product Highlights

• 169° diagonal field of view: The 1.5mm focal length provides an exceptionally broad viewing angle for applications where maximum scene coverage is important.
• Compact M12 x 0.5 mounting: The standard M12 interface allows integration into compact camera modules and embedded vision equipment.
• 1/4-inch image format: Optimized for VGA-class imaging sensors with a maximum image format of Φ4.7mm.
• F2.0 fixed aperture: Provides a practical balance between optical compactness and light transmission for embedded imaging applications.
• 2G2P + IRCF construction: The optical structure integrates an infrared-cut filter component for visible-light imaging systems.

M12 Ultra Wide Angle Lens Applications

Core Application Scenes

The extremely wide field of view makes this lens particularly useful when the camera must cover a large area from a short installation distance. Its 1.5mm focal length can help reduce blind areas in compact imaging equipment, while the M12 mount supports integration into small camera housings.

• Compact CCTV and security cameras: Suitable for monitoring relatively large areas where a wide viewing angle is more important than long-distance observation.
• Automotive auxiliary vision: The ultra-wide viewing angle can be considered for compact vehicle-mounted cameras and surrounding-area observation systems where broad scene coverage is required.
• Embedded vision systems: The M12 x 0.5 mount and compact optical configuration are suitable for small embedded camera modules used in smart devices and monitoring equipment.
• Machine vision: Can be used in applications that require a broad inspection area from a relatively short working distance, particularly when VGA resolution is sufficient.
• Robotics and mobile equipment: The wide FOV can support environmental observation and navigation-related imaging where a large portion of the surrounding scene needs to be captured.

Designed for compact wide-angle imaging applications, this lens is best suited to systems where broad scene coverage and small camera size are key design requirements.

How to Select This 1.5mm M12 Ultra Wide Angle Lens

The extremely short 1.5mm focal length should be selected when the imaging system requires very broad scene coverage rather than narrow, long-distance observation. At a 1/4-inch format, this lens provides 169° diagonal, 137° horizontal, and 112° vertical FOV.

Because the lens has a TV distortion specification of less than -17%, it should be evaluated carefully when geometric accuracy is critical. For applications such as general monitoring, environmental observation, and wide-area embedded imaging, this level of distortion may be acceptable depending on the image-processing pipeline. For applications requiring highly accurate dimensional measurement, a lower-distortion optical design may be more appropriate. See TOWIN’s Distortion Guide for more information.

The FOV Calculator can also be used to estimate how focal length and sensor dimensions affect the expected viewing area before selecting the final lens.
