Abstract

A special type light cone with the surface being coated with a nano-film mainly comprises a cone body, a large end and a small end, wherein surfaces of the large end and the small end are coated with a broadband antireflection nano-film of which the wave band being 300-2000 nm and the thickness ranging from 50 nm to 500 nm, and a conical surface of the solid cone body is coated with a SiO2 / ZrO2 film system high-reflectivity nano-film of which the thickness ranging from 100 nm to 1000 nm. The light cone provided by the present invention is made of ordinary crown glass. The special type light cone has the advantages of being simple in structure, easy to manufacture, high in coupling efficiency and low in cost, and is applicable to occasions such as light beam reception and light beam coupling and sensing.

Description

technical field [0001] The invention relates to an optical passive device, especially an optical cone. Background technique [0002] With the continuous expansion of the application scale of wireless optical communication, laser radar, light source and optical fiber coupling, the system also puts forward higher requirements for optical signal reception, such as high sensitivity, high coupling efficiency, wide-angle reception, etc. Especially in complex application environments, factors such as weather conditions, atmospheric turbulence, and base vibration can easily affect the optical signal receiving and coupling efficiency of the system. However, the conventional optical signal receiving technology is often only suitable for workplaces where the influence of environmental factors is weak. Usually, photodetectors or optical fibers are used to directly receive the focused spatial optical signal, which cannot achieve high-sensitivity wide-angle reception, which will directly ...
