Abstract

The invention discloses a selectively converging optical device. The optical device comprises a selective reflecting coating (1), an upper light guide layer (2), a light-to-frequency conversion coating (3), a lower light guide layer (4), a reflective layer (5) and an encapsulation protective layer (6) which are overlapped sequentially from top to bottom, wherein one side of the optical device is an emergent surface (7), and other sides are the reflective layer (5) and the encapsulation protective layer (6) from the inside to the outside. The selectively converging optical device can be used for converging light and emitting light with the same wavelength on the emergent surface.

Description

Technical field [0001] The invention relates to an optical device capable of selecting wavelengths for convergent output, which can convert incident light on a light-receiving surface into light of a specific wavelength, and converge and output on a fixed end surface of the optical device. Background technique [0002] The convergence of light is of great significance to optical devices and light energy utilization. Convergence of light in the sense of traditional geometric optics usually has two forms: one is converging through transmission and refraction, that is, using a certain geometrical lens or Fresnel lens to refract the light, and regularly change the propagation direction of parallel light so as to Focus produces convergence. One is to converge by reflection, that is, concave mirrors such as parabolic mirrors and spherical mirrors are used to reflect incident parallel light to make the light converge at the focal point. However, the above two types of geometric optics...
