Compared to sphero cylindrical lenses, aspheric lenses are the best choice if other factors are considered in the optical setup, such as high image quality, numerical aperture, or space savings. Aspheric lenses are rotationally symmetric optical elements with a radius of curvature that deviates radially from the center of the lens. Due to this special surface geometry, the difference between aspheric lenses and sphero cylindrical lenses, aspheric lenses can significantly improve the imaging quality of optical systems.

Sphero cylindrical lenses and aspheric lenses, their different radii of curvature lead to deviations from spherical lenses. Description of Spherical and Aspheric Optical Effective Area Generally, as long as the lens radius deviates from the spherical shape, it is an aspheric lens.
The incident beams intersect at a common focus, preventing spherical aberration. Therefore, an aspheric lens is a better focusing optics. In contrast, the incident beam of a sphero cylindrical lens is more strongly deflected with increasing distance from the optical axis and does not intersect at a common point, causing aberrations that lead to blurred images, so the use of an aspherical surface Lenses improves image quality.
Through the above introduction and analysis of the difference between sphero cylindrical lens and aspheric lens, hope it helps you.
