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 21):
A method for cutting a multilayer material, comprising the steps of:\n (1) a splitter module splitting an incident light beam into a first polarized light beam and a second polarized light beam; (2) the first polarized light beam and the second polarized light beam passing through an uniaxial crystal element individually by having the first polarized light beam corresponding to a first refractive index and the second polarized light beam corresponding to a second refractive index different to the first refractive index; so that the first polarized light beam has a first focus, and the second polarized light beam has a second focus; a focal length of the first focus being different to that of the second focus, a focus difference existing between the first focus and the second focus; and (3) the first focus and the second focus being located individually on a surface of a first layer structure and another surface of a second layer structure of a multilayer material, respectively.
