Sphero cylindrical lens manufacturers tell you that spherical lenses have a wide range of applications. Sphero cylindrical lens manufacturers tell you that spherical lenses can be used in e.g. metrology, aerospace (spectroscopes mounted inside satellites) or medical technology (slit lamps used to examine the anterior segment).

The sphero cylindrical lens manufacturer tells you that the spherical lens is used to refract incoming light to the desired degree according to the shape, scattering or focusing characteristics of the spherical lens. In imaging systems, where high image quality is accompanied by low imaging errors, spherical aberration can also be reduced by selecting the effective aperture, which is caused by blocking other incident rays with stronger peripheral light intensity.
In addition, sphero cylindrical lens manufacturers tell you that using multiple spherical lenses can also improve image quality, but the spatial conditions of the optical system must be considered. Achromatic can be achieved by combining one or more condenser and dispersive lenses, usually using a low-refractive-index positive convex lens and a low-refractive-index negative concave lens and cementing them together to improve spherical aberration and chromatic aberration in optical systems such as achromatic Chromatic aberration mirrors are used in photographic lenses.
The above information is the sphero cylindrical lens manufacturer's introduction and analysis of the spherical lenses, hope it helps you.
