The embodiment of the invention provides a method for manufacturing plane double-blazing grating. First plane blazing grating with a first blazing angle and second plane blazing grating with a secondblazing angle are manufactured, and the plane double-blazing grating can be manufactured through splicing and replication of the two pieces of plane blazing grating with the first blazing angle and the second blazing angle. The manufacturing method is high in grating efficiency and high in wavefront quality; the manufactured double-blazing grating is high in finished product rate and is easy to implement; the method for manufacturing the plane double-blazing grating is high in flexibility and is not limited by factors such as the grating blazing angle and the grating area; and the manufactureddouble-blazing grating slips the leash of an adjusting mechanism, the position and the posture of the grating are not changed any more in the storage process, and the grating is flexible and convenient in the use process. 本发明
