Method for manufacturing aspherical prism and aspherical prism

An aspherical prism, comprising:

• a first surface and a second surface that are perpendicular to each other;
• and
• a reflective surface connecting the first surface with the second surface,
• wherein at least one of the first surface or the second surface is an aspherical surface, and
• the aspherical prism is manufactured by a method for manufacturing an aspherical prism, and
• the method comprises:
• step S1, forming a prism and a lens into one piece to obtain a forming body glass by using a hot-pressing molding,
• step S2, adhering the forming body glass to a tooling, and performing a right-angle surface milling on the forming body glass according to a preset size while reserving a processing amount for a polishing process,
• step S3, adhering the forming body glass formed after the right-angle surface milling to an optical backing plate for polishing,
• step S4, cutting the forming body glass formed after the polishing,
• step S5, coating the forming body glass formed after the cutting, and
• step S6, inking the forming body glass formed after the coating.
