The sphero cylindrical lens manufacturer tells you that the shape of the spherical surface of the spherical lens corresponds to the section of the sphere, and the sphere is a rotationally symmetric optical element, and the distance between its radius of curvature and the geometric center is constant. The sphero cylindrical lens manufacturer tells you that this means that the optically effective area can be described by specifying only one parameter, the radius R. Since this parameter is constant over the entire surface, the sphere has a relatively economical cost advantage in manufacturing.

The sphero cylindrical lens manufacturer tells you that the optical effective area of ​​the sphere is described by the radius, and the spherical lens has obvious advantages in terms of production cost. This is due to the uniform shape of the sphere ensuring a simple manufacturing process and shorter production times.
sphero cylindrical lens manufacturers tell you that spherical lenses are suitable for fast generation of optical inspection and uniform measurement. Measurements such as tactile measurement methods (such as profilometers or 3D coordinate measuring machines), as well as optical measurement methods such as interferometers and computer-generated holograms (CGH), are all chosen for measurement using spherical lenses.
The above information is the sphero cylindrical lens manufacturer's introduction and analysis of the spherical lenses, hope it helps you.
