Basic Knowledge of Machine Vision: Overview And Classification of Optical Lenses
Optical lens is generally called camera lens or photographic lens, lens for short, its function is optical imaging. The lens is an important component in the machine vision system and has a key role in imaging quality.

Features Of Aspheric Lens
The spherical lens has the congenital defect of spherical aberration, which brings about the insurmountable flare phenomenon. Obviously, it will affect the image quality. With aspheric lenses, the light can be accurately projected at one point by refraction of the light through the higher-order curved surface.

Composition of Infrared Lens
Optical compensation zoom system: when several groups of lenses are used for zooming and compensation in the zoom objective, the movement of each lens group is carried out at the same speed and the same speed, so only a simple mechanical structure is required to connect each lens group together Just do linear motion.

Which People are Suitable for Spherical Lenses and Aspheric Lenses
We often hear that many people worry about choosing spherical lenses and aspheric lenses. What is the difference between spherical lenses and aspheric lenses? Who are they suitable for?

How To Choose Spherical and Aspherical Lenses And The Difference Between The Two
As the name implies, the surface curvature of an aspheric lens is different from that of ordinary spherical lenses. In order to pursue the thinness of the lens, the curved surface of the lens needs to be changed. In the past, the spherical design was used to increase the aberration and distortion, resulting in obvious image blur.
