2.5mm M9 Wide Angle Lens Applications

Core Application Scenes

This 2.5mm M9 wide angle lens is designed for embedded cameras where a small optical package needs to cover a relatively large nearby scene. With the AR1335 sensor, it provides a 103° diagonal and 84° horizontal FOV, allowing one compact camera module to monitor a broad area without requiring a longer installation distance.

The lens is particularly useful for compact scene-monitoring devices and embedded vision modules where physical space is limited. Its 10 × 10mm holder and 9.95mm TTL allow the optical assembly to fit into small camera housings, while the 2.5mm focal length provides broad coverage for nearby targets.

The dual image-format compatibility also gives OEM developers greater flexibility when designing camera modules around different sensors. With AR1335, the lens reaches its wider 103° diagonal FOV; with OV5640, it provides an 89° diagonal FOV. This makes it practical for camera designs where the same basic optical platform may be evaluated with different sensor configurations.

Designed for compact wide-angle embedded cameras and broad-area close-range imaging applications.

When evaluating sensor and lens combinations, the Sensor Guide can help engineers understand how image format affects optical performance. For projects requiring a specific coverage area, the FOV Calculator can be used to compare focal length and field-of-view requirements.

Wide-Angle Performance & Optical Considerations

The most distinctive feature of this lens is its different FOV performance across the two supported sensors. With the AR1335 sensor, the 2.5mm focal length produces a 103° diagonal FOV, 84° horizontal FOV, and 66° vertical FOV. With the OV5640, the corresponding FOV is 89° diagonal, 68° horizontal, and 53° vertical.

This difference demonstrates why sensor size should be considered when selecting a miniature wide angle lens. A larger image format can utilize a wider portion of the optical image circle, changing the resulting field of view. Engineers can use the Focal Length Calculator when comparing focal length requirements for different camera configurations.

The AR1335 configuration specifies TV distortion below -2.5%, while the OV5640 configuration specifies below -1%. These values should be considered during system design, particularly when the camera is used for geometric analysis or computer vision algorithms that rely on predictable image geometry.

The lens also features a 1G5P + IRCF optical construction. The IRCF configuration is intended to control infrared wavelengths in compatible visible-light camera modules. Its F4.3 aperture provides a defined fixed optical configuration for applications where compact mechanical integration is prioritized.

Frequently Asked Questions

Q: Which sensors are compatible with this 2.5mm M9 lens?
A: The lens supports 1/3.2″ and 1/4″ image formats, with specific FOV data provided for the AR1335 and OV5640 sensors.

Q: What is the maximum field of view of this lens?
A: With the AR1335 sensor, the lens provides a 103° diagonal, 84° horizontal, and 66° vertical field of view.

Q: What is the FOV with the OV5640 sensor?
A: With OV5640, the lens provides an 89° diagonal, 68° horizontal, and 53° vertical FOV.

Q: Why is the FOV different between AR1335 and OV5640?
A: The two sensors have different image formats and active image areas. Even with the same 2.5mm focal length, the utilized portion of the optical image circle changes, resulting in different fields of view.

Q: Is this a fisheye lens?
A: No. Although the AR1335 configuration reaches a 103° diagonal FOV, the supplied specifications do not identify the lens as fisheye. It is better positioned as a compact wide angle lens with controlled distortion.

Q: Is this lens suitable for embedded machine vision?
A: Yes. Its 5MP resolution, compact M9 mounting configuration, broad FOV, and small 10 × 10mm holder make it suitable for selected embedded machine vision and visual sensing applications.

Q: What does the 10 × 10mm holder provide?
A: The compact holder helps minimize the mechanical footprint of the camera module, making the lens suitable for small embedded devices and space-constrained optical assemblies.

Q: What is the optical structure of this lens?
A: The lens uses a 1G5P + IRCF optical construction, combining glass and polymer optical elements with an infrared-cut filter configuration.
