Low Distortion Lens – M501515008820F

M501515008820F is Low-distortion wide-angle CCTV lens with Built-In IR Filter, 94.5° F2.0 1/5″ M5X0.25-mount, suitable for surveillance and imaging applications.

1.59mm M5 Low Distortion Lens

This 1.59mm M5 wide angle lens is a compact fixed focal lens designed for miniature imaging systems that require a broad field of view with controlled distortion. Supporting 2MP resolution and a 94.5° diagonal FOV on a 1/5″ sensor, it delivers wide-area imaging while maintaining TV distortion below 1.5%. The F2.0 aperture also provides a practical balance between light transmission and compact optical design for embedded cameras and space-constrained vision devices.

M5 Low Distortion Lens Highlights

• 94.5° diagonal FOV for broad-area image coverage from a compact lens.
• <1.5% TV distortion helps maintain accurate image geometry.
• 1.59mm fixed focal length provides an ultra-wide perspective for miniature cameras.
• F2.0 aperture supports practical light collection in compact imaging systems.
• M5 × 0.25 mount is suitable for space-constrained embedded camera designs.

1.59mm M5 Low Distortion Lens Applications

Core Application Scenes

This 1.59mm M5 wide angle lens is designed for compact imaging equipment where a conventional longer focal length lens cannot provide sufficient scene coverage. Its 94.5° diagonal field of view allows a small camera module to capture a relatively broad area while its <1.5% TV distortion helps preserve the shape and position of objects near the image edges.

The lens is particularly suitable for miniature embedded cameras, compact monitoring modules, smart IoT devices, robotic sensing modules, and space-constrained visual systems. The short 1.59 mm focal length enables the camera to view close‑range areas without substantially enlarging the optical assembly.

For embedded vision applications, the M5 × 0.25 mount provides a compact mechanical interface, while the integrated IRCF structure helps support camera modules requiring infrared-cut optical filtering. Its wide FOV, low‑distortion performance and compact mounting suit applications constrained by limited installation space and required image coverage.

Designed for compact wide-angle embedded imaging and space-constrained camera applications.

Frequently Asked Questions

Q: What type of lens is the 1.59mm M5 lens?
A: It is a fixed focal wide angle lens with a 1.59mm focal length, 94.5° diagonal FOV on a 1/5″ sensor, and less than 1.5% TV distortion.

Q: Is this lens a fisheye lens?
A: No. Although the lens provides a wide 94.5° diagonal field of view, its TV distortion is controlled below 1.5%, so it is better classified as a wide angle low distortion lens rather than a fisheye lens.

Q: What sensor size is this lens designed for?
A: The lens is specified for a 1/5″ image format and provides the stated FOV and optical performance based on this sensor format.

Q: What is the field of view of this 1.59mm lens?
A: On a 1/5″ sensor, the lens provides approximately 94.5° diagonal, 88° horizontal, and 66° vertical field of view.

Q: What does the <1.5% TV distortion specification mean?
A: It indicates that the lens maintains relatively controlled geometric distortion across its image field, which is useful when straight-line reproduction and image geometry are important.

Q: What is the advantage of the F2.0 aperture?
A: The F2.0 aperture provides a practical balance between light collection and compact optical construction, helping the lens work effectively in embedded imaging systems with limited space.

Q: What type of mounting interface does this lens use?
A: This lens uses an M5 × 0.25 mounting thread, making it suitable for miniature camera assemblies and customized compact optical housings.

Q: Can this lens be customized for a specific camera module?
A: Custom optical and mechanical configurations can be evaluated according to the required sensor, field of view, mounting interface, housing dimensions, and application requirements. For project-specific requirements, contact Towin through the Contact page.
