1.Introduction of self-focusing lenses

Self-focusing lens or grin lens is an optic that is able to modify the form of an optical device, while altering its focal distance. The primary purpose of this lens is to alter the distance from your image and the plane of focus, at various distances and sizes of objects to achieve the functions of auto-focus and zoom.

2.self-focusing lens parameters

If you’re using a self-focusing lens it is crucial to know the specifications for the lenses. The following are typical characteristics of a self-focusing lens:

1. The focal length can be described as the important parameter in self-focusing lenses. It refers to the distance light is able to reach the imaging plane of the lens after it has been focused on the lens. The focal length unit is typically millimeter.

2. Aperture: Aperture is a second crucial aspect of a self-focusing camera, that refers to the amount of light that passes through the lens. The bigger your aperture the greater amount of light is absorbed by the lens and the clearer the image appears on the plane of focus.

3. Zoom range: The term “Zoom range” refers to the distance in which self-focusing lenses can focus. Certain lenses with high-end features can expand or reduce their focal length 2 times or more.

4. Motor that focuses The focusing function of a self-focusing lens typically accomplished through motor. The motor’s parameters comprise speed, precision and noise.
