Wide Angle Lens – S03612710024F

S03612710024F is 3.6mm High-Quality wide angle lens with Built-In Filter, 3-megapixel resolution CCTV lens, F2.4 aperture M12/S-mount lens.

Product Introduction

This 3.6mm 3MP M12 wide angle lens is designed for compact imaging systems that require broad scene coverage, flexible sensor compatibility, and reliable close-to-medium distance imaging. Supporting both 1/2.7″ and 1/3″ image formats, the lens provides different field-of-view performance according to the connected sensor, making it suitable for embedded vision cameras, compact machine vision devices, smart monitoring equipment, and other space-constrained imaging applications.

With a 3.6mm focal length, F2.4 aperture, M12×0.5 mount, and 0.2m minimum object distance, this fixed focal lens provides a practical balance between wide-angle coverage and image stability. At 1/2.7″, it delivers a 121° diagonal FOV, while the 1/3″ format provides a 107° diagonal FOV. The 5G+IRCF optical construction further supports compact optical integration where an IR-cut filter is required.

M12 Wide Angle Lens Core Highlights

• Dual Sensor Compatibility: Supports both 1/2.7″ and 1/3″ image formats for greater camera design flexibility.
• Wide-Angle 3.6mm Focal Length: Provides up to 121° diagonal FOV on a 1/2.7″ sensor for broad scene coverage.
• 3MP Imaging: Suitable for compact vision systems requiring more detailed imaging than standard 2MP solutions.
• Close-Focus Capability: A 0.2m minimum object distance supports applications where objects need to be captured from relatively short working distances.
• Compact M12 Integration: The M12×0.5 mount simplifies integration into compact embedded cameras and industrial imaging devices.

M12 Wide Angle Lens Applications

Wide-Angle Imaging for Compact Vision Systems

The combination of a 3.6mm focal length and wide field of view makes this lens suitable for applications where the camera must cover a relatively large area without significantly increasing the physical size of the imaging system. The 121° diagonal FOV available with a 1/2.7″ sensor can be useful for monitoring areas, detecting objects across a broad scene, and capturing spatial information in compact equipment.

The 1/3″ compatibility provides additional flexibility for camera manufacturers working with smaller sensors. Its 107° diagonal FOV and <-25% distortion specification provide a different optical balance when paired with a 1/3″ image sensor.

Designed for Compact Machine Vision Application

This lens is Designed for compact machine vision application where installation space is limited but a wider viewing area is required. The 3MP resolution, fixed focal configuration, and 0.2m M.O.D. make it suitable for inspection and detection tasks where the camera needs to observe objects at relatively short distances.

Optical Performance & Selection Considerations

Two Sensor Formats, Different FOV Performance

The lens supports both 1/2.7″ and 1/3″ image formats, but the resulting field of view is different. With a 1/2.7″ sensor, the lens provides 121° diagonal, 100° horizontal, and 52° vertical FOV. With a 1/3″ sensor, the corresponding FOV is 107° diagonal, 85° horizontal, and 54° vertical.

This makes sensor selection an important part of system design. Camera manufacturers should evaluate the actual sensor size, required coverage, working distance, and image area before finalizing the optical configuration. TOWIN’s FOV Calculator can also be used to estimate coverage for different lens and sensor combinations.

Distortion and Wide-Angle Design

The lens has a specified distortion of <-33% with a 1/2.7″ sensor and <-25% with a 1/3″ sensor. These figures reflect its wide-angle optical design rather than a low-distortion architecture.

For applications such as general wide-area monitoring, presence detection, and broad scene observation, this level of distortion may be acceptable. However, applications requiring accurate dimensional measurement, geometric inspection, or precision positioning should evaluate distortion requirements carefully. Refer to the distortion guide when selecting an optical solution.

Frequently Asked Questions

Q: What sensors are compatible with this 3.6mm M12 lens?
A: The lens supports both 1/2.7″ and 1/3″ image formats, with different FOV and distortion performance for each sensor size.

Q: What is the field of view of this M12 wide angle lens?
A: With a 1/2.7″ sensor, the lens provides 121° diagonal, 100° horizontal, and 52° vertical FOV. With a 1/3″ sensor, it provides 107° diagonal, 85° horizontal, and 54° vertical FOV.

Q: Is this a low distortion lens?
A: No. With distortion specified at <-33% for 1/2.7″ and <-25% for 1/3″, this lens should be considered a wide-angle lens rather than a precision low-distortion lens.

Q: What is the minimum object distance of this lens?
A: The M.O.D. is 0.2m, making the lens suitable for relatively close-range imaging and compact equipment where the camera is installed near the target.

Q: What mount does this lens use?
A: The lens uses an M12×0.5 mount, a common interface for compact embedded cameras, industrial cameras, and machine vision modules.

Q: Is this lens suitable for machine vision?
A: Yes. Its 3MP resolution, wide FOV, 0.2m M.O.D., and compact M12 mount make it suitable for selected machine vision and industrial inspection systems, particularly where broad scene coverage is more important than precision geometric measurement.

Q: What does IRCF mean in the optical structure?
A: IRCF indicates that an IR-cut filter is incorporated into the optical construction. It should not be interpreted as the same as an IR-corrected lens designed to maintain focus across visible and infrared wavelengths.

Q: Where can I find other M12 wide-angle lens options?
A: You can explore TOWIN’s M12 lens product range to compare different focal lengths, sensor formats, resolutions, and optical configurations.
