実用新案登録請求の範囲第１項記載のレーザ加工
用射出装置。[Claims for Utility Model Registration] (1) A collimator lens that receives a laser beam transmitted from a laser oscillator via an optical fiber and converts it into a parallel laser beam; a cylindrical lens that forms an elliptical condensed laser beam in the direction;
A laser processing device characterized by comprising a slit that shapes the laser beam from the cylindrical lens into a rectangular shape, and a condensing lens that forms an image of the shape of the slit. (2) Registration of a utility model characterized in that a beam expander is added that receives a parallel laser beam from the collimator lens, converts it into a parallel beam of a specific magnification, and sends it to the cylindrical lens. An injection device for laser processing according to claim 1.
