5.5mm M12 Wide Angle Lens Applications

Automotive Imaging

The combination of a 5.5mm focal length, 83° diagonal FOV, F1.8 aperture, and IP69K protection makes this lens suitable for vehicle-mounted camera systems operating in demanding environments.

Potential applications include:

• Automotive monitoring cameras
• Vehicle-mounted vision systems
• Parking and maneuvering cameras
• Side-view cameras
• Outdoor vehicle cameras
• Industrial vehicle imaging
• Specialized perception cameras

The relatively moderate wide-angle FOV provides broad scene coverage while avoiding the extreme viewing geometry of fisheye optics.

For automotive vision applications, see the ADAS Vision solution.

940nm Near-Infrared Imaging

One of the key features of this lens is its Visible + 940nm Pass Filter. This optical configuration is intended for applications where controlled transmission around the 940nm wavelength is required.

Potential applications include:

• 940nm illumination camera systems
• Near-infrared machine vision
• Active illumination imaging
• Smart monitoring devices
• Optical sensing systems
• Specialized automotive cameras
• Embedded NIR imaging modules

When designing a camera around a 940nm light source, the filter transmission characteristics should be evaluated together with the sensor’s quantum efficiency and the illumination wavelength.

For additional optical design information, see TOWIN’s Optical Design resources.

Outdoor and Harsh-Environment Imaging

The IP69K rating makes this lens suitable for camera systems that may be exposed to dust, water spray, high-pressure cleaning, and other demanding environmental conditions.

Potential applications include:

• Outdoor monitoring cameras
• Agricultural equipment
• Construction machinery
• Industrial vehicles
• Smart infrastructure
• Harsh-environment embedded cameras

The environmental protection makes it particularly suitable for camera modules installed outside conventional protected enclosures.

Designed for automotive, outdoor, and visible/940nm near-infrared imaging applications requiring wide scene coverage and IP69K environmental protection.

Compact Embedded Camera Systems

The M12x0.5 mount, 21.04mm TTL, and 0.2m MOD make this lens suitable for compact camera assemblies where installation space is limited.

Compatible systems may include:

• M12 camera modules
• 5MP embedded cameras
• Compact CMOS imaging modules
• NIR camera systems
• Robotics cameras
• Industrial vision modules
• Vehicle-mounted camera modules

When matching the lens with an image sensor, the Sensor Guide can help evaluate sensor format and optical compatibility.

Spectral Filtering Considerations

The Visible + 940nm Pass Filter differentiates this lens from conventional visible-light camera lenses. It is designed around a specific spectral transmission requirement rather than simply providing standard visible-light imaging.

For systems using 940nm LEDs or other near-infrared illumination, the camera designer should consider:

• Sensor sensitivity at 940nm
• LED illumination wavelength
• Required optical transmission
• Ambient light conditions
• Exposure settings
• Required image contrast

The filter should not be described as an IR-corrected optical design. IR correction concerns wavelength-dependent focal shift, whereas this product specification describes a spectral pass-filter configuration.
