1.0mm M2.6 Miniature Wide Angle Lens Applications

Core Application Scenes

This 1.0mm M2.6 wide angle lens is specifically suited to miniature camera systems where mechanical space is one of the primary design constraints. Its 3.3 mm total optical length and M2.6 × 0.15 mounting interface let users fit this lens into extremely small camera housings, avoiding the bulky mechanical footprint typical of conventional larger‑format lenses.

The 94° diagonal field of view makes it useful for short-range embedded imaging, particularly when a compact camera needs to monitor a relatively broad area. Typical applications can include miniature IoT cameras, compact electronic devices, small inspection modules, access-control equipment, and embedded visual sensors using 1/9″ VGA image sensors.

The fixed F3.5 aperture provides a simple optical configuration for applications where the lens does not need variable iris adjustment. Its >37% relative illumination and CRA below 17° are also relevant when matching the optical output to a small image sensor.

The integrated IRCF (Infrared Cut Filter) is important for camera modules designed for visible-light imaging because it helps suppress unwanted infrared wavelengths reaching the sensor. This makes the lens particularly suitable for compact color-camera modules where the optical assembly must remain simple and space-efficient.

Designed for ultra-compact embedded cameras and short-range wide-angle imaging applications.

When designing a miniature camera, matching the lens image format to the sensor is essential. The Sensor Guide explains key sensor and lens matching considerations, while the Lens Basics section provides additional information about focal length, FOV, aperture, and other fundamental optical parameters.

For applications where the required viewing coverage needs to be calculated before selecting the lens, the FOV Calculator can be used to evaluate the relationship between sensor size, focal length, and field of view.

Frequently Asked Questions

Q: What type of lens is the 1.0mm M2.6 lens?
A: This miniature wide‑angle fixed‑focal lens targets 1/9″ VGA camera modules. It delivers a 1.0 mm focal length and a 94° diagonal field of view.

Q: Is this lens a fisheye lens?
A: No. Although the lens provides a relatively wide 94° diagonal FOV, the available specifications do not indicate a fisheye optical design. It is therefore classified as a miniature wide angle lens.

Q: What sensor format is this lens designed for?
A: The lens is specified for a 1/9″ image format and VGA resolution.

Q: What is the field of view of the 1.0mm lens?
A: On the specified 1/9″ image format, the lens provides approximately 94° diagonal, 78° horizontal, and 62° vertical field of view.

Q: What does the 3.3mm TTL specification mean?
A: TTL, or total track length, describes the overall optical track length of the lens assembly. A 3.3mm TTL makes this lens suitable for applications with very limited internal optical space.

Q: What is the purpose of the IRCF in this lens?
A: IRCF refers to an infrared cut filter. It helps reduce unwanted infrared wavelengths entering the image sensor and is commonly used in visible-light camera modules.

Q: What mounting thread does this lens use?
A: The lens uses an M2.6 × 0.15 mounting thread, which is suitable for miniature camera and embedded optical assemblies.

Q: Can this lens be customized for a specific miniature camera module?
A: Custom optical and mechanical configurations can be evaluated based on sensor format, focal length, FOV, mounting thread, TTL, housing dimensions, and application requirements. For a project-specific inquiry, contact Towin through the Contact page.
