Low Distortion Lens – S04812506240F

S04812506240F is Low distortion Wide-angle 8-Megapixel lens with Built-In IR Filter, 1/2.5″ M12x0.35 mount 74° diagonal FOV for security surveillance.

M12 4.8mm 8MP Low Distortion Lens

This 4.8mm M12 low distortion lens is designed for 1/2.5″ sensors requiring 8MP high-resolution imaging with controlled geometric distortion. With distortion below 0.5%, a 74° diagonal FOV, and a compact M12 × 0.35 mount, it provides a reliable optical solution for machine vision, industrial imaging, and compact embedded camera systems.

The combination of an 8MP optical design, 1/2.5″ image format, and distortion below 0.5% makes this lens suitable for applications where detailed image capture and controlled image geometry are both important. Engineers can refer to the Sensor Guide when matching this lens with a suitable CMOS sensor.

M12 4.8mm Low Distortion Lens Applications

Core Application Scenes

This 8MP M12 low distortion lens is designed for compact vision systems that require a balance between image coverage, resolution, and geometric accuracy. Its 4.8mm focal length provides a 74° diagonal field of view on a 1/2.5″ sensor, allowing the camera to capture a useful working area without relying on an extreme wide-angle or fisheye optical configuration.

The lens is particularly suitable for compact machine vision inspection systems where image detail is important but the camera must remain relatively close to the inspection target. The 0.2m minimum object distance supports close-range imaging, while the <0.5% distortion specification helps maintain more consistent object geometry for visual inspection and positioning tasks.

For embedded industrial cameras installed inside machinery or equipment, the M12 × 0.35 mounting interface provides a compact mechanical solution. The 8MP resolution also makes the lens suitable for applications where small features need to remain visible within the captured image.

The F4.0 fixed aperture provides a stable optical configuration for controlled industrial environments with sufficient illumination. For applications where working distance and required field of view need to be calculated before lens selection, the FOV Calculator can be used to evaluate the relationship between sensor size, focal length, and viewing area.

Frequently Asked Questions

Q: What sensor size is this M12 lens designed for?
A: This lens is designed for a 1/2.5″ image format and provides 8MP resolution for compatible CMOS imaging systems.

Q: What is the focal length and field of view of this lens?
A: The lens has a fixed 4.8mm focal length and provides a 74° diagonal, 62° horizontal, and 49° vertical field of view on the specified image format.

Q: Is this an M12 low distortion lens?
A: Yes. The specified distortion is below 0.5%, making the lens suitable for applications where controlled geometric distortion is important.

Q: Is this lens suitable for 8MP machine vision cameras?
A: Yes. Built for 8MP imaging, this lens delivers high resolution with controlled distortion for compact machine‑vision and industrial‑imaging systems.

Q: What is the minimum object distance of this lens?
A: The specified M.O.D. is 0.2m, allowing the lens to be used for relatively close-range imaging applications.

Q: What type of mount does this lens use?
A: It uses an M12 × 0.35 threaded mount, which is commonly used in compact embedded camera and machine vision modules.

Q: Does the IRCF specification mean that this is an IR corrected lens?
A: No. IRCF stands for IR Cut Filter, distinct from IR‑corrected optics. Per given specs, this lens is not an IR‑corrected lens.

Q: Is this lens a fisheye lens?
A: No. Its 74° diagonal field of view and distortion below 0.5% are more consistent with a controlled low distortion fixed focal length design rather than a fisheye lens.
