Cell mirror design principle and function

[Abstract]:
Because the application field of cell mirror is not very wide, the telecentric lens has always been mysterious and not well-known. The design principle of the telecentric lens is introduced below.

Because the application field of cell mirror is not very wide, the telecentric lens has always been mysterious and not well-known. The design principle of the telecentric lens is introduced below.

Cell mirror

Cell mirror is a lens specially designed to correct the parallax of traditional lenses. It can be within a certain range of object distance, so that the magnification of the obtained image will not change with the change of object distance. This is not the same object to be measured. The situation on the surface is very important application.

The convergence center of the cell mirror rays parallel to the optical axis of the principal rays is located at infinity in the image side, which is called: the telecentric optical path in the object side. Its function is: it can eliminate the reading error caused by the inaccurate focusing of the object side. It combines the dual functions of the object-side/image-side telecentricity. Mainly used in the field of visual measurement and inspection.

It can be seen from the above design principles of various types of Cell mirrors that the telecentric lens is a high-precision lens designed to fully utilize the characteristics of optical imaging and fully consider the influence of light in imaging. has been widely used.
