Wide Angle Lens – CCL140205MPF

CCL140205MPF is 2.05mm High-Resolution low distortion wide-angle lens with Built-In Filter, F2.6 M7X0.35 mount lens, 1/4″ 5-megapixel CCTV lens.

The 2.05mm focal length provides a broad viewing angle on the 1/4″ OV5640 sensor while maintaining a compact optical configuration. The 5MP resolution makes this lens suitable for applications that require more image detail than conventional low-resolution miniature camera modules.

For projects where sensor size and optical coverage must be matched carefully, the Sensor Guide can help engineers evaluate sensor and lens compatibility before selecting the final optical configuration.

2.05mm 5MP M7 Wide Angle Miniature Lens

This compact 2.05mm M7 wide angle lens is designed for 1/4″ sensors and delivers a 110° diagonal field of view with 5MP resolution. With a small M7×0.35 mount, fixed F2.6 aperture, manual focus, and an integrated IR cut filter, it is well suited to compact embedded cameras, industrial imaging modules, and space-constrained vision devices.

For engineers selecting a compact lens for a small CMOS sensor, the M8/M7/M6 miniature lens range provides a practical platform for integrating wide-angle imaging into compact camera assemblies.

Wide Angle Lens Applications

Core Application Scenes

This 2.05mm 5MP M7 wide angle lens is particularly suitable for compact camera systems where installation space is limited but a broad viewing area is required. Its 92° horizontal and 71° vertical FOV provide wide scene coverage without requiring a physically large lens assembly.

For compact embedded vision devices, the lens can be integrated into small inspection cameras, smart sensing modules, compact monitoring devices, and machine vision systems that need to observe a relatively large area from a short working distance.

The 0.2m minimum object distance also makes it practical for near-field imaging where the camera needs to monitor objects positioned relatively close to the optical module. The fixed F2.6 aperture and manual focus configuration provide a straightforward optical solution for applications with a controlled installation distance.

For broader industrial vision projects, Towin’s Machine Vision solution provides additional guidance on integrating industrial lenses with cameras and vision systems.

Compatible Device List

• Compact CMOS camera modules: Designed around 1/4″ sensors such as the OV5640 and similar small-format image sensors.
• Embedded vision equipment: Suitable for compact AI vision modules, edge cameras, and embedded imaging devices where lens size is a key mechanical constraint.
• Industrial monitoring cameras: The wide FOV can help compact monitoring devices cover a larger area without requiring multiple camera modules.
• Robotic and sensing modules: Suitable for compact robotic vision or perception modules where broad scene coverage is required within a restricted mechanical envelope.
• Near-field imaging systems: The 0.2m M.O.D. supports applications that need to observe objects relatively close to the camera.

For applications requiring more precise field-of-view planning, the FOV Calculator can be used to estimate image coverage based on sensor and lens parameters. Engineers can also use the Focal Length Calculator when comparing focal-length requirements for a specific camera setup.

Designed for compact wide-angle embedded vision, industrial sensing, and near-field imaging applications.

Optical Design Considerations

The combination of a 2.05mm focal length and 1/4″ image format produces a wide viewing angle while keeping the optical package compact. This makes the lens particularly useful when a camera enclosure has limited internal space but still requires broad scene coverage.

The -6% TV distortion is a characteristic to consider when the lens is used for measurement or geometrically sensitive imaging. For applications where distortion performance is a critical selection factor, engineers can review Towin’s Distortion Guide before finalizing the optical configuration.

The integrated IR cut filter is intended for visible-light imaging rather than infrared-transmission imaging. Therefore, this model is a suitable choice for daylight or controlled visible-spectrum camera systems where suppression of unwanted near-infrared response is required.

For projects involving custom optical requirements, including changes to mechanical dimensions, coatings, focus configuration, or optical performance, customers can contact Towin Lens to discuss the required configuration.
