Abstract

The invention relates to an alignment adjusting device of optical fiber collimators. A distance adjusting guide rail mechanism and an alignment adjusting guide rail mechanism, which are perpendicular to each other, are arranged on a base, and an extension line of the distance adjusting guide rail mechanism is intersected with the alignment adjusting guide rail mechanism, so the movement locus of a distance adjusting sliding block and an alignment adjusting sliding block is T-shaped, and fastening structures which are consistent in height and used for paralleling or overlapping the extension directions of the optical fiber collimators are arranged on the distance adjusting sliding block and the alignment adjusting sliding block. Therefore, when the alignment adjusting device is used, on the premise that two optical fiber collimators are consistent in height and the extension directions are parallel or overlapped, distance and alignment are adjustable, so the problem of difficulty in alignment of the optical fiber collimators in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of optical communication, in particular to an alignment adjustment device for an optical fiber collimator. Background technique [0002] The fiber collimator is an optical passive device, which is composed of an optical fiber and a self-focusing lens. It can convert the light output from the optical fiber into parallel light, and can also couple the parallel light from the outside into the optical fiber. In the field of optical absorption gas sensors, the paired use of fiber optic collimators is a very common optical coupling method. The alignment adjustment effect of two fiber optic collimators and the distance between them have a great influence on the coupling efficiency of light and the sensor performance. The detection sensitivity has a direct impact, but since there is no corresponding special device to align the light collimator in the prior art, the alignment difficulty and low precision of the light...
