4 Overview of the lens under test

Office copiers copier lens as a child member can object to the naked eye observation/distance of distinct vision in forming a clear and readable Like. Printable image formed on the film, paper or other materials. Size images can be equated with an actual object to be copied to be put In or out. The lens is the lens copiers installed in the copier, the user can not replace. It contains two types of copiers. Article A class copiers, image side and object side slits parallel to each other and relative to the camera stationary. By moving the lens relative to the object image and the slit, You can scan the entire object image plane. Adjust the lens direction, the same direction so that the best performance of the reference angle lens and the slit opening. At any time, Content is copied, not the entire test pattern, but part of the test pattern through the slit. The second category copiers, keeping things like the mirror surface Head is fixed, use a scanning or pulsed lighting systems, test the lens at various angles to the reference object imaging situation. Two kinds Lens copiers, may all be composed of refractive surfaces, but also by a combination of refraction and a reflective surface (such as. 1 catadioptric lens). Simultaneously, Both types of copiers can be folded flat mirror through the optical path, as shown in FIG. ......
