Fixing device for pigtail and probe of a portable Raman spectrometer

Abstract

The invention discloses an apparatus for fixing the tail fiber and the probe of a portable Raman spectrometer. The apparatus comprises an upper cover of a case for disposing the Raman spectrometer, the upper cover is a hollow box body, one side of the upper cover is connected with a cover plate through a loose leaf, the cover plate is buckled to the upper cover, the cavity of the upper cover is filled with foam, a tail fiber groove for placing the tail fiber and a probe groove for placing the probe are correspondingly dug in the foam, and the locus of the tail fiber groove has an arc shape. The apparatus allows the tail fiber and the probe to be firmly and reliably fixed, so the shake of the probe and the tail fiber in the case is prevented; and the hollow space in the upper cover is utilized to dispose the tail fiber and the probe, so the volume of the whole case is saved, thereby the whole case is compact and portable. Grooves for preventing the shake of the tail fiber and the probe are made by using the foam, and the locus of the tail fiber groove is composed of a plurality of segments of arcs, so the tail fiber can be effectively protected from excessive bending damages.

Description

technical field [0001] The invention relates to a fixing device for a tail fiber and a probe of a Raman spectrometer, in particular to a fixing device for a tail fiber and a probe of a portable Raman spectrometer. Background technique [0002] With the development of science and technology, Raman spectrometers are becoming small and intelligent, and more and more portable Raman spectrometers are appearing on the market. In order to effectively protect the Raman spectrometer, shockproof, waterproof, etc., and for portability, the portable Raman spectrometer often uses a standard safety box as the casing of the portable Raman spectrometer. In order to meet the needs of different testing occasions, portable Raman spectrometers generally have longer pigtails to flexibly test samples at different positions. The standard safety box has limited volume, and the pigtail is long and cannot be bent too much. How to fix the pigtail is a difficult problem. Existing portable Raman spect...

Problems solved by technology

However, this method cannot provide better fixation during transportation, and it is easy to shake. The probe often collides with the box wall, which reduces the reliability of the optical components in the probe.

In addition, pressing the probe and pigtail into the groove will easily cause the fiber to bend, the curvature is too small, and the fiber will be damaged
