Metal reflector and manufacturing method thereof

Abstract

The invention discloses a metal reflector which comprises a closed substrate, a mirror surface arranged on the surface of one end of the substrate, an internal interlayer lightweight structure and a back plate arranged on the surface of the other end of the base body. The mirror surface comprises a surface modification layer, a reflecting layer and a protective layer, and the protective layer is the outermost layer; the interlayer lightweight structure comprises a plurality of cavities and through holes connected through the cavities. An additive manufacturing and processing technology is adopted, so that the interlayer light-weight structure in the metal reflector is more flexible, the metal reflector not only meets the high-rigidity design of the reflector, but also is light in weight due to the interlayer light-weight structure; the integrated design is adopted; the design of the surface modification layer enables the precision to be defined as that the RMS value of the deviation value between the precision and an ideal surface is superior to 1/10 lambda, wherein lambda is equal to 632.8 nm; the design of the transition layer enhances the chemical and mechanical durability of the metal reflector, and improves the bonding strength between the metal reflector substrate and the surface modification layer.

AI Technical Summary

Benefits of technology

This technology allows for flexibility in adding layers on metals without making them heavier by reducing their thickness or increasing its density. It achieves this through modifying certain properties such as reflectivity, coloring agents, crystal orientation, etc., resulting in improved optical performance compared with previous methods like plasma spray coatings. Additionally, there are technical benefits associated with removing unwanted materials during production instead of relying solely upon grinding techniques. Overall, these improvements improve the quality control and efficiency of producing laminated structures made up entirely of different types of material together.

Problems solved by technology

This patented technical solution involves reducing the size or thickness of certain parts within an optoelectrooptic device's lens assembly without compromising its performance. By doing away with conventional techniques like millings, drilling, etchants, etc., these new ways allow for better control over how much space they require while still maintaining their desired properties.
