THIN MESH, MANUFACTURING METHOD THEREOF AND MANUFACTURING DEVICE THEREFOR

摘要

The present invention provides meshes and a manufacturing method which enable one to use wide varieties of materials excellent in anticorrosiveness, chemical resistance and safety for a human body and to form the mesh holes and the cross section in arbitrary shapes. A light beam emitted by an excimer laser oscillator (12) is shaped by a an aperture pattern (2) and irradiated through an optical system comprising an objective (3) on a thin material (5) composed of high polymers such as polysulfone, polyester etc., which is fixed on a work stage (4). The image of the aperture pattern (2) projected on the thin material (5) drills a plurality of mesh holes. This process can be applied to, for example, the thin mesh (7) for an inhaler.
