2.8mm or 4.5mm Low Distortion M12 Board Lenses
Low Distortion M12 Board Lens, is designed with a small distortion less than 3% at the edges, while the focal length is short at 2.8mm to 5.5mm. It is with aspherical optical elements to reach this function and best used for some applications that hope to reduce the distortion as more as possible, such as measuring or some auto detective devices.

This model is with visible and NIR light Confocal design, so it is good to be used with IR light sources. Its high resolution assure a good image quality in day or night versions.
