Abstract

The invention provides a double-fiber reflection type collimator and industrial equipment. The device comprises a lens, a first fiber, a second fiber and a filter. A first end surface and a second endsurface are respectively arranged at two ends of the lens in the light path direction; the first end surface is arranged in a convex spherical arc shape; the first optical fiber and the second optical fiber are respectively welded with the second end surface; the first optical fiber and the second optical fiber are symmetrically arranged about the optical axis of the lens; the filter is plated with a transflective film on the end surface opposite to the first end surface; and the characteristics of the transflective film comprise light transmission of a first wavelength and light reflection of a second wavelength. The lens is directly welded through the optical fiber; the area of an interface where light is incident to air is increased, the power density is reduced, and the problem that the end surface of the optical fiber is prone to being burnt down in high power is solved; and the filter is easier to assemble and more stable due to the fact that no 8-degree air gap exists between the optical fiber and the lens and incident and reflected light paths are symmetrical.

Description

technical field [0001] The invention relates to the field of optical equipment, in particular to a dual-fiber reflective collimator and industrial equipment. Background technique [0002] The collimator is an optical component used for input and output of fiber optic devices. The divergent light device emitted by the fiber becomes parallel light through the front convex lens. Its function is to couple the light into the required device with maximum efficiency. Medium or easy acceptance of optical signals for maximum efficiency. refer to figure 1 , figure 1 It is the optical path structure diagram of the existing dual-fiber reflective collimator. The dual-fiber reflective collimator includes a C-lens lens 11, an optical device 12, and a C-lens lens 13 arranged along the optical path. There is an 8-degree slope, and the C-lens lens 11 is arranged in a double pigtail arrangement. [0003] In some applications, the optical power reaches 10 watts or even higher, and the power...
