Elliptical Lens

An elliptical lens is an optical element with a curved surface that has two focal points located on the same plane. In lighting, the design produces an asymmetrical distribution of light in one direction. This type of lens is most commonly used in imaging systems due to its ability to create an image with good resolution and contrast. Elliptical lenses are often used in telescopes, microscopes, cameras, projectors and other devices that require precise light beams or illuminated images. They can also be used to correct optical aberrations such as spherical aberration and chromatic aberration.
