Description

technical field [0001] The invention relates to the technical field of optical systems, in particular to an optical device suitable for laser direct writing exposure equipment. Background technique [0002] In the field of direct image transfer technology, there are two relatively traditional direct image transfer technologies, one is the direct image transfer technology of DMD, and the other is the direct image transfer technology of rotating prism. [0003] Direct image transfer technology of rotating prisms. This technology mainly uses single-point scanning technology, which is inferior to the DMD direct image transfer technology mentioned below in terms of production capacity, and its processing accuracy is better than that of DMD direct image transfer technology. This technology is a patented technology of the Israeli company Orbotech, which is mainly used in circuit board LDI and other products. [0004] Using DMD's direct image transfer technology. The core compone...
