The principle and function of cylindrical mirror

The Principle and Function of 1. Cylindrical Mirror
A cylindrical mirror is a composite lens composed of a spherical surface and a cylindrical mirror. The spherical surface means that the radius of curvature in the horizontal direction is the same, and the radius of curvature in the vertical direction is different; the cylindrical mirror has a curvature value on the radius of curvature in the horizontal direction, And the radius of curvature in the vertical direction is a plane.

Cylindrical lenses can correct visual problems for people with astigmatism, myopia, hyperopia, etc. For example, someone with astigmatism in the right eye may see unclear or overlapping images. In this case, the doctor may recommend him to wear cylindrical lenses to improve vision problems. The cylindrical mirror can correct visual problems by focusing the light so that the light passing through the cylindrical mirror can be focused to the correct point.

Application fields of 2. cylindrical mirrors
In addition to the medical field, cylindrical lenses are also widely used in other fields. The following are a few application areas for cylindrical mirrors:

1. Camera field: As one of the important components of some cameras, cylindrical lens can help photographers optimize the imaging effect of photos.

2. Lighting field: The application of cylindrical mirror in the field of lighting is becoming more and more common, most of which are used for the spotlight and sprinkle of lighting projects.

3. The field of laser technology: The field of laser technology requires the use of cylindrical mirrors to adjust the shape and direction of the laser beam so that the laser produces the required output.

In short, the cylindrical lens is a kind of multifunctional lens, not only can be used in the medical field of vision correction, but also can be used in the field of camera, lighting and laser technology, has a wide range of applications.
