Low Distortion Lens – M803012508822F

M803012508822F is Low-distortion 5-Megapixel wide-angle CCTV lens with Built-In IR Filter, 3.0mm F2.2 M8x0.35 mount, for security surveillance.

3.0mm M8 Low Distortion Lens

This 3.0mm M8 low distortion wide angle lens is a 5MP fixed focal miniature lens designed for compact camera modules requiring broad scene coverage and controlled geometric distortion. It supports both 1/2.5″ and 1/2.9″ sensors, delivering up to 103° diagonal FOV on a 1/2.5″ sensor while maintaining distortion below -0.8%. With an M8 × 0.35 mount, F2.2 aperture, 14.8mm TTL, and integrated IRCF, it is well suited for space-constrained embedded imaging systems.

3.0mm M8 Low Distortion Lens Applications

Core Application Scenes

This 3.0mm M8 low distortion wide angle lens is designed for compact imaging systems that need a broad field of view without the pronounced geometric distortion commonly associated with ultra-wide optical designs. When used with a 1/2.5″ sensor, it provides a 103° diagonal FOV, while the same lens provides a 90° diagonal FOV on a 1/2.9″ sensor.

The combination of 5MP resolution and controlled distortion below -0.8% makes this lens suitable for embedded camera modules where image detail and spatial consistency are both important. It can be integrated into compact smart devices, robotic sensing modules, IoT vision equipment, miniature monitoring cameras, and other embedded systems where the optical assembly must remain relatively small.

The M8 × 0.35 mounting interface and 14.8mm TTL are particularly useful when designing camera modules with restricted mechanical space. The integrated IRCF structure is also suitable for camera architectures requiring infrared-cut filtering as part of the optical assembly.

For system designers comparing miniature wide-angle optics, sensor size has a direct effect on the resulting field of view. The difference between the 103° diagonal FOV on 1/2.5″ and 90° on 1/2.9″ illustrates why sensor matching should be evaluated during lens selection. Towin’s Sensor Guide provides additional information for evaluating lens and sensor compatibility.

Frequently Asked Questions

Q: What type of lens is this 3.0mm M8 lens?
A: It is a fixed focal wide angle lens designed for miniature camera systems, supporting 5MP resolution and sensor formats from 1/2.5″ to 1/2.9″.

Q: Is the 3.0mm M8 lens a fisheye lens?
A: No. Delivering a 103° diagonal FOV for the 1/2.5″ sensor, it features distortion under ‑0.8%, classifying it as a low‑distortion wide‑angle lens, not a fisheye lens.

Q: What field of view does this lens provide?
A: On a 1/2.5″ sensor, the lens provides 103° diagonal, 88° horizontal, and 70° vertical FOV. On a 1/2.9″ sensor, it provides 90° diagonal, 81° horizontal, and 56° vertical FOV.

Q: What sensors are compatible with this lens?
A: The lens is specified for both 1/2.5″ and 1/2.9″ image formats. The actual FOV changes according to the sensor format.

Q: What is the advantage of the < -0.8% distortion specification?
A: Low distortion delivers accurate image geometry, ideal for wide‑scene applications without severe straight‑line bending.

Q: What does the M8 × 0.35 mount mean?
A: M8 × 0.35 specifies the mechanical mounting thread of the lens, with an 8mm nominal diameter and 0.35mm thread pitch. It is intended for miniature camera and embedded optical assemblies.

Q: What does IRCF mean in this lens specification?
A: IRCF refers to an infrared-cut filter incorporated into the optical structure. It helps limit infrared wavelengths reaching the image sensor in applications using conventional visible-light imaging.

Q: Can this lens be customized for a specific camera module?
A: Custom optical and mechanical configurations can be evaluated based on the required sensor format, FOV, distortion, mounting interface, dimensions, and application. For project requirements, engineers can contact Towin for further discussion.
