IR Corrected Wide Angle Lens Applications

IR-Enhanced Smart Security Cameras

The 3.5mm focal length and 125° diagonal FOV make this lens suitable for security cameras that need to cover a relatively broad area from a compact installation position. The IR corrected optical design is particularly valuable in systems that use near-infrared illumination for low-light or nighttime imaging.

Unlike a conventional visible-light-only lens, an IR corrected lens is designed to reduce focus shift between different wavelengths, helping maintain sharper images when the imaging system switches between visible and near-infrared operation.

Designed for wide-angle day-and-night security imaging applications.

Near-Infrared Embedded Vision

Embedded cameras used in intelligent devices may operate with both visible illumination and near-infrared light. The IR corrected optical configuration makes this lens suitable for systems where maintaining consistent image focus across these wavelengths is important.

Potential applications include smart monitoring devices, intelligent access systems, compact sensing equipment, and embedded cameras equipped with near-infrared illumination.

Wide-Area Machine Vision

The 103° horizontal FOV provides broad scene coverage for compact inspection and monitoring systems. It can be considered when a machine vision camera needs to observe a relatively large working area without using an extremely short focal length.

For industrial imaging projects, this lens can complement TOWIN’s Machine Vision solutions.

Robotics and Mobile Vision

Robotic systems operating in changing lighting conditions may benefit from an IR corrected lens when their vision modules use visible and near-infrared illumination. The wide FOV also helps compact robots observe a larger surrounding area.

The manual focus configuration allows the lens to be adjusted during camera integration to suit the robot’s working distance and mechanical installation.

For robotics applications, see TOWIN’s Robotics Vision solutions.

Compact Access and Recognition Systems

Wide-angle IR corrected lenses can be useful in compact access-control and recognition devices where the camera must capture people or objects within a relatively broad viewing zone.

The combination of 1/2.3″ sensor compatibility, 3MP resolution, 103° horizontal FOV, and IR corrected focusing makes this lens suitable for selected embedded recognition and monitoring systems.

IR Corrected Optical Performance

One of the defining characteristics of this product is its IR corrected optical design.

Different wavelengths of light can focus at different positions because of chromatic aberration. In imaging systems that use both visible light and near-infrared illumination, this can result in focus changes when the illumination wavelength changes.

An IR corrected lens is designed to compensate for this behavior and maintain more consistent focus across the intended wavelength range. This makes the technology particularly useful for day-and-night cameras, near-infrared vision systems, and other applications where visible and IR imaging are both required.

Sensor & Field-of-View Matching

This lens is designed for a 1/2.3″ image format and provides:

• 125° diagonal FOV
• 103° horizontal FOV
• 67° vertical FOV

The 3.5mm focal length provides substantially wider coverage than longer focal length M12 lenses, making it suitable for applications where the camera needs to capture a broad area.

When selecting the sensor and lens combination, engineers should consider sensor format, required image coverage, working distance, and camera installation position together.

TOWIN’s Sensor Guide provides additional information about matching lenses with camera sensors.
