Dental light guide rod for beam homogenization

Abstract

A dental light guide rod with a beam homogenizing function, comprising a light guide rod (1), a light collimator, a housing (3), and a laser handle (4). The housing (3) is sleeved on the laser handle (4), and a free end thereof is connected to the light guide rod (1); in the housing (3), the light collimator is provided between a light-emitting end of the laser handle (4) and an end of the light guide rod (1); light emitted from the light-emitting end of the laser handle (4) enters an end face of the light guide rod (1) in parallel after passing through the light collimator; a plurality of optical fibers (7) is arranged densely in the light guide rod (1); the light collimator can be a collimating lens (2). The light emitted from a light source is collimated into parallel light and then enters the light guide rod, so that the problem that the brightness distribution of light beams emitted from the light guide rod is not uniform under the condition of direct incidence is solved.

Description

technical field [0001] The invention relates to the field of dental medical instruments, in particular to a dental light guide rod for homogenizing light beams. Background technique [0002] In some dental applications, it is necessary to use a light guide rod to transmit the LED light or laser beam to the treatment area. The traditional optical coupling method between the light source and the light guide rod is generally a direct method, that is, directly transmit the light emitted by the light source. irradiated to the light-incoming end face of the light guide rod, but if Figure 11 As shown, the beam emitted in this way has the problem that the beam energy is concentrated at the center within the working distance, but there is no solution to this problem in the prior art, and this uneven distribution of light intensity is not conducive to dentistry. Treatment operations affect the treatment effect. Contents of the invention [0003] The purpose of the present inventio...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a dental light guide rod with homogenized beams. After the light emitted by the light source is collimated into parallel light, and then incident into the light guide rod, it can solve the problem that the light guide rod exits directly. The problem of uneven distribution of beam brightness
