2.7mm M5 Low Distortion Lens Applications

Core Application Scenes

This 2.7mm M5 low distortion lens is designed for compact camera systems where maintaining image geometry is more important than achieving an extremely wide viewing angle. With distortion controlled below 1.5%, it can help reduce the geometric deformation commonly associated with compact short-focal-length optics, making it suitable for applications where the relative shape and position of objects should remain consistent across the image.

The 18mm minimum object distance gives this lens a particular advantage in close-range embedded imaging. It can be installed near the target area while maintaining a defined imaging distance, making it suitable for compact electronic equipment, small inspection modules, access-control devices, smart sensing equipment, and other embedded camera systems.

The lens is specified for the GC0308 sensor with a 648 × 488 resolution and a 1/6.5″ image format. Its M5 × 0.35 mounting thread and 0.97mm B.F.L. also provide clear mechanical parameters for integration into a customized camera housing.

The fixed F3.6 aperture simplifies optical configuration where variable iris control is unnecessary. The integrated IRCF further supports visible-light camera modules by filtering unwanted infrared wavelengths before they reach the image sensor.

Designed for compact close-range imaging systems requiring controlled geometric distortion and stable optical performance.

For applications requiring a different mounting interface or optical format, Towin’s Other Mount Lenses provides additional compact lens configurations.

When selecting a lens for a small image sensor, the sensor format and optical image circle should be considered together. Towin’s Sensor Guide provides guidance on matching camera sensors with appropriate lenses.

For applications where distortion is an important selection factor, the Distortion Guide provides additional information about lens distortion and its effect on image geometry. Engineers can also use the Lens Selection Guide when comparing focal length, sensor format, distortion, and other optical specifications.

If you need to evaluate the relationship between focal length, sensor dimensions, and field of view before selecting a lens, Towin’s FOV Calculator can be used during the camera design process.

Frequently Asked Questions

Q: What type of lens is the 2.7mm M5 lens?
A: It is a low distortion fixed focal lens designed for compact 1/6.5″ camera modules, with less than 1.5% distortion.

Q: Is this a wide angle lens?
A: No. Its specified 52° diagonal, 44° horizontal, and 34° vertical FOV provide a moderate viewing angle rather than an ultra-wide perspective. It is better positioned as a low distortion fixed focal lens.

Q: What sensor is this lens designed for?
A: The lens is specified for a 1/6.5″ image format and provides the listed field of view based on the GC0308 sensor configuration.

Q: What is the resolution of this lens?
A: The specified resolution is 648 × 488, matching the listed GC0308 camera configuration.

Q: What is the distortion level of this lens?
A: The lens has a specified distortion of less than 1.5%, making controlled geometric distortion one of its primary optical characteristics.

Q: What is the minimum object distance?
A: The M.O.D. is 18mm, allowing the lens to be used for relatively close-range imaging where the camera is positioned near the target.

Q: What is the purpose of the IRCF?
A: IRCF stands for infrared cut filter. It helps block unwanted infrared wavelengths from reaching the image sensor and is commonly used in visible-light camera modules.

Q: What mounting thread does this lens use?
A: The lens uses an M5 × 0.35 mounting thread, making it suitable for compact camera assemblies and customized optical housings.
