Patent ID: 7841847

Claim:
A system for manufacturing a micro-retarder, the system comprising: a carrying device for carrying an optically anisotropic polymolecule film; a heating device for providing a heating source; a conical lens and a focusing lens for deflecting an energy formed by the heating source, the energy to be applied to the polymolecule film, so that the energy formed in the central area of the heating source is smaller than that in the peripheral area of the heating source, wherein the energy changes to a valley distribution curve from a Gaussian distribution curve through the conical lens and changes to an inverse Gaussian distribution curve from the valley distribution curve through the focusing lens, so that the energy formed in the central area of the laser beam is smaller than that in the peripheral area; and a movement control device for controlling the polymolecule film and the heating source to relatively move along a first direction, so that the adjusted heating source heats at least one partial area of the polymolecule film along the first direction and resumes the partial area of the polymolecule film to be optically isotropic.
