Low Distortion Lens – M803412807822F

M803412807822F is Low-distortion wide-angle 8-Megapixel CCTV lens with Built-In IR Filter, 1/2.8″ format, M8x0.35 mount, F2.2 aperture for high-quality security surveillance.

3.4mm M8 8MP Low Distortion Lens

This 3.4mm M8 low distortion wide angle lens is designed for compact 8MP camera modules using the Sony IMX415 sensor. With an 86° diagonal FOV, F2.2 fixed aperture, and TV distortion below -0.4%, it combines broad scene coverage with controlled image geometry in a compact M8 package.

The lens uses an M8x0.35 mount, 14.3mm total track length, and 1G4P optical structure, making it suitable for space-constrained embedded camera systems that require 8MP imaging performance. For more information about compact lens formats, see our M8/M7/M6 Miniature Lenses.

M8 Low Distortion Lens Highlights

• 8MP imaging for IMX415: Designed to support high-resolution image capture from 1/2.8″ Sony IMX415 sensors.
• 86° diagonal wide angle FOV: Provides broad scene coverage while maintaining a compact 3.4mm focal length.
• Low geometric distortion: TV distortion below -0.4% helps preserve more accurate object geometry than conventional wide-angle designs.
• Compact M8 construction: The M8x0.35 mount and 14.3mm TTL are well suited to miniature camera assemblies.
• F2.2 fixed aperture: Provides a consistent optical configuration for embedded camera applications.

3.4mm M8 Low Distortion Lens Applications

Core Application Scenes

• Compact surveillance and monitoring: The 86° diagonal field of view helps capture a relatively broad scene from a small camera enclosure, while the low distortion specification helps maintain recognizable object shapes.
• Embedded vision systems: The M8x0.35 mount and 14.3mm TTL make the lens suitable for compact camera modules where installation space is limited.
• Smart equipment monitoring: The 3.4mm focal length provides useful coverage for monitoring equipment areas, workspaces, access points, and enclosed environments.
• Robotic observation: The combination of 8MP resolution and controlled distortion can support visual observation tasks where both scene coverage and image geometry are important. See our Robotics Vision solutions for related optical applications.
• Compact intelligent camera modules: The lens can be integrated into small-form-factor imaging devices that require higher-resolution image capture without using a larger C-mount optical assembly.

Designed for compact 8MP camera applications where wide coverage, low distortion, and a small mechanical footprint need to be balanced in the same optical system.

For projects where sensor size, field of view, and focal length need to be matched precisely, our Lens Selection Guide provides additional optical selection information. You can also use the FOV Calculator to estimate the relationship between focal length, sensor format, and field of view.

Optical Performance and Lens Selection

The 3.4mm focal length provides an 86° diagonal FOV on the IMX415 sensor, making this lens suitable for applications that need broader coverage than a standard narrow-angle lens.

At the same time, the TV distortion is specified below -0.4%, which places the lens in the low-distortion category. This is particularly useful when image geometry matters, such as object measurement, visual inspection, or structured scene analysis.

Because wide-angle performance varies with sensor dimensions, users should evaluate the actual horizontal and vertical FOV rather than selecting a lens from focal length alone. Our Sensor Guide can help when matching the optical format to a camera sensor.

Frequently Asked Questions

Q: What sensor is this 3.4mm M8 lens designed for?
A: It is specified for the 1/2.8″ Sony IMX415 sensor and supports 8MP imaging performance.

Q: What is the field of view of this M8 lens?
A: On the IMX415, the specified FOV is 86° diagonal, 78° horizontal, and 50° vertical.

Q: Is this lens a low distortion lens?
A: Yes. The specified TV distortion is below -0.4%, making it suitable for applications where controlled geometric distortion is important.

Q: Is this a fisheye lens?
A: No. Based on the supplied optical specifications, this lens is classified as a wide angle low distortion lens rather than a fisheye lens.

Q: What mount does this lens use?
A: It uses an M8x0.35 mount, which is commonly used in compact miniature camera modules.

Q: Is the aperture adjustable?
A: No. The lens uses a fixed F2.2 aperture, providing a consistent optical configuration.

Q: What is the minimum object distance?
A: The specified minimum object distance is 0.2m.

Q: Does IRCF mean the lens is IR corrected?
A: No. IRCF indicates an IR cut filter structure. It should not be interpreted as an IR-corrected optical design. For optical selection involving infrared imaging, refer to the relevant Lens Basics resources or contact TOWIN for application-specific requirements.
