6mm M4 Miniature Fixed Focal Lens Applications

Core Application Scenes

This 6mm miniature fixed focal lens is designed for compact camera modules that require a more controlled viewing area than an ultra-wide-angle lens. With a 48° diagonal field of view and 38° horizontal field of view on a 1/4″ sensor, it is suitable for applications where the camera needs to focus on a defined target area rather than capture an expansive scene.

The 6mm focal length can be useful in close-to-medium-range embedded imaging, particularly where the target occupies a specific portion of the camera frame. The 0.2m minimum object distance provides flexibility for cameras installed relatively close to equipment, components, or inspection targets.

Its M4 × 0.35 miniature mount and 9.7mm total track length make the lens suitable for compact OEM camera modules and equipment-integrated imaging systems. Compared with larger C-Mount or CS-Mount optics, the miniature mechanical interface can help simplify camera integration when installation space is restricted.

For industrial applications, the lens can be considered for equipment monitoring, component observation, compact inspection modules, and automated imaging devices where a fixed optical configuration is preferred for consistent installation and repeatable imaging.

Designed for compact embedded imaging and close-to-medium-range industrial observation applications.

Compatible Device List

• 1/4″ CMOS Camera Modules: Designed for compact camera systems using 1/4″ image sensors.
• Embedded Industrial Cameras: It fits equipment‑integrated imaging modules that rely on a fixed field of view.
• Compact Inspection Devices: The 6 mm focal length enables targeted observation of components and equipment at relatively close working distances.
• Robotics Imaging Modules: The small M4 mounting interface can support integration into space-constrained robotic camera assemblies.
• OEM Camera Systems: Suitable for customized imaging products requiring a fixed focal length and compact optical package.

Before integrating the lens into a new camera design, engineers can use the FOV Calculator to estimate the actual scene coverage based on sensor dimensions, focal length, and working distance.

For additional guidance on selecting a suitable focal length and sensor combination, the Lens Selection Guide can help engineers evaluate the main optical parameters.

Optical Configuration

The lens uses a 3G optical structure and a fixed F4.5 aperture. This configuration delivers a simple optical solution for camera modules that need no variable iris control.

The specified <19% distortion should be considered when designing the imaging system. This lens does not target low‑distortion optical performance. Instead, it serves applications that prioritize its compact form factor, focal length, and defined field of view over ultra‑low geometric distortion.

For applications where image distortion is a critical design factor, engineers can review the Distortion Guide before selecting an optical configuration.

Integration & Customization

The M4 × 0.35 mount provides a compact mechanical interface for miniature camera assemblies. Boasting a 9.7 mm total track length and 0.2 m minimum object distance, the lens fits applications that require the camera to view a defined target from a relatively short mounting distance.

Frequently Asked Questions

Q: What sensor size is this 6mm lens designed for?
A: This lens is designed for 1/4″ image sensors and provides a 48° diagonal field of view.

Q: What is the field of view of the lens?
A: The lens provides a 48° diagonal FOV, 38° horizontal FOV, and 29° vertical FOV on the specified image format.

Q: Is this a wide angle lens?
A: No. With a 48° diagonal and 38° horizontal field of view, this lens is better described as a compact fixed focal lens with a controlled viewing angle rather than a dedicated wide angle lens.

Q: Is this a low distortion lens?
A: No. The specified distortion is below 19%, so the lens should not be positioned as a low-distortion lens. Applications requiring very low geometric distortion should use an optical design specifically optimized for low distortion.

Q: What is the minimum object distance?
A: The minimum object distance is 0.2m, making the lens suitable for relatively close-range imaging.

Q: What mount does this lens use?
A: The lens uses an M4 × 0.35 mount, which is intended for compact and miniature camera assemblies.

Q: What is the resolution of this lens?
A: The specified resolution is 2MP, making it suitable for standard-detail imaging applications and compact embedded camera systems.

Q: Can this lens be used in an OEM camera module?
A: Yes. Its compact M4 × 0.35 mount, fixed 6mm focal length, and 9.7mm total track length make it suitable for customized embedded camera designs. Specific sensor and mechanical compatibility should be verified during system integration.
