car rear view mirror

Rearview mirrors are divided by their installation positions, including exterior rearview mirrors, lower rearview mirrors and interior rearview mirrors. Divided by use, the exterior rearview mirror reflects the rear side of the car, the lower rearview mirror reflects the front and bottom of the car, and the interior rearview mirror reflects the rear and interior conditions of the car. Depending on the purpose, the mirror structure will also be different. Generally, there are two main types of rearview mirror mirrors. One is a plane mirror. As the name suggests, the mirror surface is flat. The terminology is "surface curvature radius R is infinite".

This is the same as a general household mirror, which can obtain an image of the same size as the visual size. This kind of flat mirror is often used as an interior rearview mirror. The other is a convex mirror. The mirror surface is spherical and has different radii of curvature. Its image is smaller than the visual field, but its field of view is large. It is similar to the function of a camera's "wide-angle mirror". This convex mirror is often used as an exterior rearview mirror. and lower rearview mirror. Cars and other light passenger vehicles are generally equipped with exterior rearview mirrors and interior rearview mirrors, and large commercial vehicles (buses and trucks) are generally equipped with exterior rearview mirrors, lower rearview mirrors, and interior rearview mirrors.
