3.5mm M8 8MP Low Distortion Lens Applications

Core Application Scenes

This 3.5mm M8 low distortion lens is designed for compact high-resolution camera modules that need a relatively wide viewing area without the pronounced geometric deformation associated with fisheye optics. Its 89° diagonal field of view allows a single camera to cover a broad nearby scene, while the <0.5% TV distortion specification helps maintain controlled image geometry.

The lens is particularly suitable for embedded monitoring cameras, compact smart vision devices, robotic observation modules, IoT imaging equipment, and small-form-factor visual sensing systems. Boasting a 0.2 m minimum object distance, it also fits scenarios where cameras sit relatively close to monitored subjects, including equipment observation, compact work areas, and near‑field environmental sensing.

The 14.49mm TTL provides a different mechanical profile from ultra-short miniature optical assemblies. This makes the lens suitable for camera designs where the available optical depth allows a longer lens package while still requiring the small M8 × 0.35 mounting interface.

For applications using the Sony IMX415, the combination of 8MP resolution and an 89° diagonal field of view provides a balance between image detail and scene coverage. This lens therefore works well for systems that prioritize image coverage across a wider area over an extremely narrow field of view.

Designed for compact 8MP embedded imaging systems requiring wide scene coverage and controlled optical distortion.

Lens Selection & Integration

When selecting an 8MP lens for the IMX415, the sensor format, image circle, focal length, and required field of view should be evaluated together. The specified lens provides an 89° diagonal FOV and 80° horizontal FOV on the IMX415 configuration, making it appropriate for relatively broad scene capture.

Towin’s Sensor Guide provides guidance on sensor and lens compatibility, while the Lens Selection Guide covers key factors such as focal length, FOV, resolution, and optical performance.

For projects where the required viewing area needs to be calculated from the camera distance and sensor configuration, the FOV Calculator can assist with field-of-view estimation. The Focal Length Calculator can also be used when engineers need to determine a suitable focal length from a target imaging distance and coverage requirement.

Optical Performance Considerations

The lens combines 8MP resolution with <0.5% TV distortion, making geometric control one of its notable characteristics. This benefits computer‑vision software, object‑recognition algorithms, and image‑analysis systems that rely on predictable image geometry to process camera output.

The optical structure is specified as 1G3P + IRCF. Here, IRCF refers to an infrared cut filter. It should not be interpreted as an IR-corrected optical design. For this reason, the product should be classified as a Low Distortion Lens rather than an IR Corrected Lens based on the supplied specifications.

Frequently Asked Questions

Q: What type of lens is this 3.5mm M8 lens?
A: It is an M8 miniature fixed focal wide angle lens designed for 8MP imaging, with an 89° diagonal FOV and TV distortion below -0.5%.

Q: Is this 3.5mm M8 lens a fisheye lens?
A: No. Its 89° diagonal FOV is wide, but the specified distortion is controlled below -0.5%. It is better classified as a wide angle low distortion lens rather than a fisheye lens.

Q: Which sensor is this lens designed for?
A: The specified configuration is designed for a 1/2.8″ Sony IMX415 sensor and provides the stated 89° diagonal, 80° horizontal, and 46° vertical FOV.

Q: What is the resolution of this M8 lens?
A: The lens is specified for 8MP imaging and is designed around the Sony IMX415 camera configuration.

Q: What is the distortion specification of the lens?
A: The specified TV distortion is below -0.5%. This controlled distortion characteristic makes the lens suitable for applications where maintaining predictable image geometry is important.

Q: What is the minimum object distance?
A: The M.O.D. is 0.2m, allowing the lens to support relatively close-range imaging applications.

Q: What does 1G3P + IRCF mean?
A: 1G3P describes the optical element construction, while IRCF refers to an infrared cut filter. IRCF does not mean that the lens is optically corrected for infrared imaging.

Q: Can this lens be customized for a different camera module?
A: Custom optical and mechanical configurations can be evaluated according to sensor size, focal length, FOV, mounting thread, housing dimensions, and other project requirements. For a specific camera project, contact Towin through the Contact page.
