IR Corrected Lens – CCL132520MP

CCL132520MP 1/3″ Low Distortion 25mm M12 IR corrected lens with 14° FOV, F2.0 aperture and <1.5% distortion for compact surveillance and vision systems.

25mm 2MP M12 IR Corrected Fixed Focal Lens

This 25mm M12 IR Corrected Lens is a compact fixed focal lens designed for imaging systems that require a narrow field of view, long focal length, and stable performance across visible and near-infrared wavelengths. With a 1/3″ image format, 2MP resolution, 14° diagonal FOV, and F2.0 aperture, the lens provides focused imaging for distant or relatively small targets. Its M12X0.5 mount makes it suitable for compact camera modules and embedded vision equipment. Designed for long-distance surveillance and compact machine vision applications, this IR corrected M12 lens helps maintain consistent image focus when imaging conditions or illumination wavelengths change.

The 25mm focal length provides a significantly narrower viewing angle than conventional wide-angle M12 lenses, making it suitable when the application needs target isolation rather than broad scene coverage. The fixed-focus configuration simplifies optical integration, while manual focus and a 0.2m minimum object distance provide flexibility during system setup.

M12 IR Corrected Lens Core Highlights

• 25mm Long Focal Length – Provides a narrow 14° diagonal FOV for focused target imaging.
• IR Corrected Optical Design – Supports imaging applications where visible and near-infrared light performance needs to remain consistent.
• F2.0 Aperture – Provides a relatively bright optical configuration for compact imaging systems.
• Compact M12X0.5 Mount – Enables integration into small camera modules and embedded vision devices.
• <1.5% Optical Distortion – Helps maintain geometric consistency for target observation and recognition.

M12 IR Corrected Lens Applications & Compatible Devices

Long-Distance Surveillance

The narrow 14° diagonal FOV and 25mm focal length make this lens suitable for surveillance systems that need to concentrate on a defined area rather than capture an ultra-wide scene. It can be integrated into compact security cameras, embedded surveillance modules, and fixed-position monitoring equipment where target isolation is important.

Smart Traffic Monitoring

The focused viewing angle can be useful for traffic monitoring applications where cameras are positioned to observe a specific lane, vehicle area, or defined roadside zone. The IR corrected design also makes the lens suitable for systems that may operate with infrared illumination or require stable imaging beyond visible-light conditions.

For broader traffic-imaging requirements, this lens can complement TOWIN’s dedicated ITS Lens solutions.

Compact Machine Vision

The 25mm focal length can be applied to machine vision systems that require a relatively narrow viewing area for inspecting specific targets. The M12X0.5 interface and compact optical format make it appropriate for embedded inspection cameras, compact automation equipment, and space-constrained vision modules.

For systems requiring higher-resolution inspection and more advanced optical configurations, see TOWIN’s Machine Vision solutions.

Infrared-Enabled Imaging

Because this lens is specifically IR corrected, it is suitable for imaging systems that combine visible-light and near-infrared imaging. This can be valuable for security cameras, smart monitoring equipment, and embedded devices using IR illumination.

How to Select a 25mm M12 IR Corrected Lens

A 25mm lens is generally selected when the camera needs a narrower field of view and more concentrated target coverage than a short-focal-length M12 lens. Before integration, engineers should consider sensor size, target distance, required field of view, working distance, resolution, and illumination conditions.

For help matching a lens to a specific sensor, see the TOWIN Sensor Guide. You can also use the FOV Calculator to estimate the required viewing coverage based on sensor and working-distance requirements.

Frequently Asked Questions

Q: What is the main advantage of this 25mm M12 lens?
A: Its 25mm focal length provides a narrow 14° diagonal FOV, allowing the camera to concentrate on a defined target area rather than capturing a wide scene.

Q: Is this 25mm M12 lens IR corrected?
A: Yes. The lens is IR corrected, making it suitable for imaging systems that need stable optical performance when using visible and near-infrared illumination.

Q: What cameras are compatible with this lens?
A: The lens uses an M12X0.5 mount and supports a 1/3″ image format, making it suitable for compatible compact camera modules and embedded imaging systems.

Q: Is this lens suitable for long-distance monitoring?
A: Yes. Its 25mm focal length and narrow 14° diagonal FOV make it suitable for monitoring defined or relatively distant targets where a wider viewing angle is not required.

Q: Does this lens have autofocus?
A: No. The specification uses manual focus, allowing the optical focus to be adjusted during camera integration and system setup.

Q: Is the lens a zoom lens?
A: No. It is a fixed focal lens with a 25mm focal length, so the viewing angle remains fixed after installation.

Q: What is the optical distortion of this lens?
A: The specified optical distortion is less than 1.5%, providing controlled geometric distortion for monitoring and imaging applications.

Q: Can this lens be customized for a specific imaging system?
A: TOWIN can evaluate optical requirements such as sensor format, focal length, FOV, mount, and wavelength requirements for customized lens development. Contact TOWIN through the Lens Solution Request page to discuss your project.
