METHOD FOR PROCESSING MICRO-OPTICS

摘要

PURPOSE: A method is provided to minutely and stably process various micro-optics and to reduce the processing time. CONSTITUTION: A mask(32) and a collecting lens(35) are adjusted the positions and an oscillator(25) is turned on. The adjusted position of the mask maximizes intensity of a beam. After the material is installed on a material stand(39), the adjusted position of the collecting lens clears the image of a material. Laser beams are intercepted by the screen of the mask except for the laser beam irradiated on the pattern part of the mask and the only laser beam on the pattern part reaches the material. The beam ablates the surface of the material after passing through the pattern part. The micro-optics(the material) forms an initial slant and a hole at a part near the upper and lower end of a mask hole, getting more distance the middle part of a mask standard line is from the middle part of the micro-optics, getting deeper processed depth is.
