Abstract:
An apparatus for cutting a multilayer material includes a splitter module and a uniaxial crystal element. The splitter module, located in a transmission path of an incident light beam, is used for splitting the incident light beam into a first polarized light beam and a second polarized light beam. The uniaxial crystal element is disposed adjacent to the splitter module and on a transmission path of the first polarized light beam and the second polarized light beam. The first polarized light beam and the second polarized light beam pass through the uniaxial crystal element individually by having the first polarized light beam and the second polarized light in correspondence to different index of refractions, so that two focuses with different focal lengths can be obtained. In addition, a method for cutting a multilayer material method is also provided.

Claim (Index 27):
The method for cutting a multilayer material of  claim 21 , wherein the step (3) further includes the step of:\n (31) basing on a distance between the surface of the first layer structure and the another surface of the second layer structure of the multilayer material to obtain the focus difference; (32) basing on the focus difference to find out a rotation angle of a distribution of refractive index for the uniaxial crystal element; (33) rotating the uniaxial crystal element by the rotation angle; (34) shading orderly the second polarized light beam and the first polarized light beam; (35) adjusting a distance between the uniaxial crystal element and the multilayer material so as to find out orderly a position of the first focus of the first polarized light beam on the surface of the first layer structure of the multilayer material and another position of the second focus of the second polarized light beam on the another surface of the second layer structure of the multilayer material; (36) adjusting the rotation angle of the uniaxial crystal element to fulfill the focus difference; (37) shading the second polarized light beam; (38) locating the first focus of the first polarized light beam onto the surface of the first layer structure of the multilayer material; and (39) emitting the first polarized light beam and the second polarized light beam to the multilayer material.
