What is the specific explanation of spherical mirror, we will introduce it to you through the following aspects:
1. Online explanation [click here to view the details of the plan].
A spherical mirror with a reflective surface that is part of the spherical surface is called a spherical mirror. Spherical mirrors are divided into two categories: convex mirrors and concave mirrors. A spherical mirror that uses the inside of a spherical surface as a reflective surface is called a concave mirror, and a spherical mirror that uses the outside of a spherical surface as a reflecting surface is called a convex mirror.

Sentence formation about spherical mirror.
1. In order to improve the performance of the spectroscopy instrument, two ellipsoidal mirrors and an ellipsoidal aberration-canceling grating are used for beam splitting.
2. All kinds of aspheric mirrors and non-spherical condensers with different aperture and relative aperture.
3. At the same time, this paper also discusses the method of obtaining all the phase information of the rough circumference on the surface of the aspheric mirror with only one optical carrier frequency interference fringe.
4. Because aspheric mirrors are much better than spherical mirrors in performance, they have been widely used in recent years, but the processing and inspection of aspheric mirrors are much more difficult than spherical mirrors.
5. Select the appropriate cavity structure, and the astigmatism of the optical mode in the folding cavity of the spherical mirror can be partially eliminated and adjusted.

Anonymous users2024-02-06Kiss you, I've been waiting for a long time Spherical lenses and aspherical lenses are two common types of spectacle lenses, and the difference between them is the radius of curvature. The curved surface of a spherical lens is a complete spherical shape, so its curvature is the same. The advantage of spherical lenses is that they are inexpensive to manufacture and are suitable for patients with low power for nearsightedness or farsightedness.
The curved surface of aspherical lenses is aspherical and has different radii of curvature. This design allows the lenses to conform more closely to the curvature of the eye, which in turn provides better visual effect and greater visual comfort. The manufacturing cost of non-Yunbalan spherical lenses is higher, but it can be applied to patients with myopia or farsightedness of various degrees, and it is better to use it for patients with astigmatism or higher power
