Wide Angle Lens – S04511808820

S04511808820-115° wide-angle 1/1.8″ F2.0 8MP 0.2m close-up capability S-mount high-resolution lens

4.5mm 8MP M12 Low Distortion Wide Angle Lens

This 4.5mm 8MP M12 wide angle lens is designed for compact imaging systems that require a broad field of view with controlled distortion. With 115° diagonal FOV on a 1/1.8″ sensor, F2.0 aperture, and less than 12.8% TV distortion, it provides a practical balance between wide-area coverage, image detail, and optical control for machine vision, AI vision, smart cameras, and embedded imaging devices.

The M12×0.5 mount and 7.65mm minimum back focal length make this fixed focal lens suitable for space-constrained camera designs and customized vision modules.

Product Core Highlights

• 115° diagonal wide FOV — Provides broad scene coverage on 1/1.8″ sensors while retaining useful image detail.
• <12.8% TV distortion — Offers controlled geometric distortion for applications that require more natural image rendering than conventional fisheye optics.
• 8MP optical performance — Supports high-resolution image capture for modern compact cameras and AI vision systems.
• F2.0 aperture — Provides a useful balance between light transmission and depth of field for indoor and controlled outdoor imaging.
• Compact M12×0.5 mount — Suitable for embedded cameras, compact vision modules, and space-limited optical assemblies.

Wide Angle Lens Applications

This 4.5mm M12 lens is well suited to applications where the camera needs to observe a relatively large area without using an extreme fisheye design. The 115° diagonal FOV on a 1/1.8″ sensor helps capture more of the surrounding scene, while the <12.8% TV distortion provides better geometric control for applications where excessive image bending can reduce visual usability.

Designed for compact machine vision and AI vision applications, this lens can be integrated into embedded inspection cameras, intelligent vision modules, autonomous equipment, robotic perception systems, smart cameras, and edge-AI imaging devices. Its 8MP resolution is suitable for applications that need both broad scene coverage and sufficient image detail for object detection, classification, positioning, or monitoring.

For systems using compact M12 optics, this lens can be considered alongside other M12 Lenses and Wide Angle Lenes solutions from TOWIN. For applications requiring controlled geometric rendering, it can also complement TOWIN’s Low Distortion Lens range.

Compatible devices include:

• Compact machine vision cameras
• Embedded AI vision cameras
• Robotic vision modules
• Smart inspection cameras
• Edge-AI imaging devices
• Intelligent monitoring cameras
• Compact industrial cameras
• Wide-area sensing cameras

The 0.2m minimum object distance also makes the lens practical for relatively close-range imaging, particularly where a compact camera must cover a broad working area without moving too far away from the target.

Frequently Asked Questions

Q: What type of lens is the 4.5mm 8MP model?
A: It is an M12 fixed focal wide angle lens with a 4.5mm focal length, 8MP resolution, F2.0 aperture, and <12.8% TV distortion.

Q: What field of view does this 4.5mm M12 lens provide?
A: On a 1/1.8″ sensor, the lens provides 115° diagonal, 88° horizontal, and 62° vertical FOV. On a 1/3″ sensor, the FOV is 71° diagonal, 55° horizontal, and 41° vertical.

Q: Is this lens suitable for machine vision applications?
A: Yes. Its 8MP resolution, broad FOV, controlled distortion, and compact M12 mount make it suitable for machine vision systems that require wide-area image capture rather than precision metrology.

Q: Is the 4.5mm lens a fisheye lens?
A: No. Although it provides a wide 115° diagonal FOV, its <12.8% TV distortion is significantly more controlled than typical fisheye optics, making it better categorized as a wide angle lens.

Q: What sensor size is this lens designed for?
A: The primary image format is 1/1.8″. It can also provide a defined FOV on a 1/3″ sensor, with 71° diagonal, 55° horizontal, and 41° vertical coverage.

Q: What is the minimum object distance of this lens?
A: The minimum object distance is 0.2m, making the lens suitable for relatively close-range imaging as well as broader scene observation.

Q: What mount does this lens use?
A: The lens uses an M12×0.5 mount, a common compact interface for embedded cameras, machine vision modules, AI cameras, and other small-form-factor imaging devices.

Q: Can TOWIN customize this M12 lens for a specific camera system?
A: TOWIN can support customized optical solutions according to sensor format, FOV, focal length, mechanical dimensions, mounting requirements, and application needs. Contact TOWIN for project-specific optical development and OEM/ODM requirements.
