Factory supplied Pinhole Lens - 1/1.7″ Low Distortion Lenses – ChuangAn

This is suitable for 1/1.7″ image sensors (such as IMX334) The low distortion lens provides various focal length options such as 3mm,4.2mm,5.7mm, and has wide-angle lens characteristics, with a maximum field of view angle of 120.6 º. Taking CH3896A as an example, this is an industrial lens with an M12 interface that can capture a horizontal field of view of 85.5 degrees, with a TV distortion of<-0.62%. Its lens structure is a mixture of glass and plastic, consisting of 4 pieces of glass and 4 pieces of plastic. It has 8 million pixels of high definition and can install various IRs, such as 650nm, IR850nm, IR940nm, IR650-850nm/DN.

To reduce optical aberration, some of the lenses even include aspheric lenses. An aspheric lens is a lens whose surface profiles are not portions of a sphere or cylinder. In photography, a lens assembly that includes an aspheric element is often called an aspherical lens. Compared to a simple lens, the more complex surface profile of an asphere can reduce or eliminate spherical aberration, as well as other optical aberrations such as astigmatism. A single aspheric lens can often replace a more complex multi-lens system.

These lenses are mainly used in the field of industrial vision, such as logistics scanning, macro detection, etc.
