Abstract

The invention provides a light trap fixing device. A detachable magnetic ring is additionally provided, and a light trap is provided with magnetism opposite to the magnetism of the magnetic ring, and the light trap is fixedly disposed in an optical spectrometer under action of magnetic force. The magnetic ring is further fixedly connected with the light trap by a screw, and the tightening degree of the arrangement of the light trap in the optical spectrometer is further enhanced. The light trap is additionally provided with a protrusion, and then the light trap can be fixedly in the same position of the optical spectrometer in every test. The pollution of the light trap is prevented, and accuracy and correctness of test data are guaranteed.

Description

technical field [0001] The invention relates to the technical field of analysis, in particular to an optical trap fixing device. Background technique [0002] In chemical analysis tests, ultraviolet-visible spectrometers are commonly used, and this spectrometer includes an important testing component - light trap. In the prior art, the light trap is fixed on the spectrometer by the clamping force of the spring clamp. However, the spring clip after long-term use will be weak, making the light trap unable to clamp tightly, making the light trap easy to slip during the test, resulting in the whiteboard of the light trap not completely covering the hole of the incident light, resulting in the collected data being completely Something wrong happened. Contents of the invention [0003] The object of the present invention is to provide an optical trap fixing device, which enhances the fastening force of the optical trap fixed on the spectrometer. [0004] The light trap fixing...
