Light waves are transverse: that is, the vibrating electric vector associated with each wave is perpendicular to the direction of propagation. A beam of unpolarized light consists of waves moving in the same direction with their electric vectors pointed in random orientations about the axis of propagation. Plane polarized light consists of waves in which the direction of vibration is the same for all waves. In circular polarization the electric vector rotates about the direction of propagation as the wave progresses. Light may be polarized by reflection or by passing it through filters, such as certain crystals, that transmit vibration in one plane but not in others.

In the realm of photography, the aspherical camera lens, commonly abbreviated as ASPH lens, represents a significant technological advancement. Unlike traditional spherical lenses, which have a smooth, curved surface, aspherical lenses incorporate non-spherical elements that deviate from the standard spherical shape. These non-spherical elements allow the lens to better focus light, reducing various optical aberrations that can affect image quality.

Define asphericeye

Spherical aberration is a common optical phenomenon that occurs in lenses with a uniform curvature, such as spherical lenses. It causes light rays passing through the edges of the lens to converge at a different focal point than those passing through the center. As a result, the image may appear blurred or lack sharpness.

The main difference between spherical and aspherical lenses lies in their curvature. Spherical lenses have a constant curvature across the entire lens surface, resembling a perfect sphere. This results in limitations in correcting various optical aberrations, which can lead to decreased image quality, especially towards the edges of the frame.
