A kind of multi-layer composite semi-transparent mirror and vehicle head-up display system

Abstract

The invention provides a multilayer composite transflective mirror. The multilayer composite transflective mirror comprises a transflective mirror transparent plastic substrate, the transflective mirror transparent plastic substrate is composed of an optical imaging surface and assembling support lugs arranged at the lower end of the optical imaging surface, the optical imaging surface and the assembling support lugs are respectively made from thermoplastic engineering plastic, an adhesion film is arranged on the surface of the optical imaging surface, the adhesion film is made from trititanium pentoxide, the lower surface of the optical imaging surface is provided with an antireflection film, the antireflection film is made from silicon dioxide, a silicon and aluminum mixture reflective film is arranged on the adhesion film, and a waterproof film is arranged on the silicon and aluminum mixture reflective film; the optical reflective surface layer is a plane, a spherical surface or a free-form surface in shape; and every assembling support leg is provided with an assembling hole. The invention further provides a vehicle-mounted head-up display system. The system has the advantagesof clear optical imaging and no double images.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a multi-layer composite material half mirror and a vehicle-mounted head-up display system. Background technique [0002] At present, optical-related technical products are increasingly playing an important role in the high-tech industry. The main optical products include optical materials, optical components, optical instruments, optical equipment, etc. Among them, the core optical components include various optical filters, Beam splitters, spherical and aspherical lenses, prisms, cylindrical mirrors, mirrors, flat windows, special-shaped windows, etc.; [0003] Different types of mirrors have the functions of focusing, magnifying, changing direction, and filtering the light path. With the rapid development of the automobile manufacturing industry in my country, the overall configuration of automobiles is getting higher and higher, and the requirements for safety are gradually i...
