Abstract

The invention discloses an optical module and electronic equipment. The optical module comprises a prism assembly, the prism assembly comprises a second prism and a third prism which are arranged in a mutually attached mode, the second prism and the third prism are respectively formed by gluing inclined planes of two right-angle prisms, and the main cross section of the second prism and the main cross section of the third prism are respectively rectangular. A second light filtering film is arranged on the gluing inclined surface of the second prism; a third light filtering film is arranged on the gluing inclined surface of the third prism; the first wave band light, the second wave band light and the third wave band light can pass through the prism assembly and are emitted from the same right-angle face of the third prism; and the right-angle face is a light emitting face. On the premise that a color combination function is achieved, the number of components of the color combination prism is reduced, and the machining and assembling difficulty of the color combination prism is lowered.

Description

technical field [0001] The present application relates to the field of optical technology, and more specifically, to an optical module and electronic equipment. Background technique [0002] With the development of technology, people have put forward higher requirements for the portability of consumer electronic products. Small size and light weight have become an important development direction of the electronic market. Based on this, currently in projectors, AR (augmented reality), VR (Virtual reality) and other optical devices, put forward higher design requirements for the design of the optical system. [0003] In optical devices such as projectors, AR, and VR, it is often necessary to combine multiple colors of light according to functional requirements. In the prior art, various combinations of filters, x cube, x plate, etc. are used. However, these methods have disadvantages such as many components, difficult processing, and high difficulty in assembly. Contents of...
