Embodiment Construction

[0025] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0026] This embodiment provides a method for protecting a diffraction grating, including the following steps.

[0027] S1, such as figure 2 As shown, the paraffin wax 1 is melted into a liquid state, and the paraffin wax 1 is 58 degree industrial paraffin particles, and the container where the paraffin particles are placed is heated to 60° C. and kept until the paraffin particles are completely melted. Conventional methods such as oven heating and hot plate heating can be used for heating.

[0028] S2, such...

Abstract

This application relates to the technical field of diffraction grating protection, and specifically discloses a protection method for diffraction gratings, including S1, melting the paraffin into a liquid state; S2, dripping the melted paraffin on the surface of the diffraction grating; S3, bonding the protective glass on the On paraffin; S4, after the paraffin is solidified, the diffraction grating and protective glass are stored and transported as a whole; S5, when needed, put the diffraction grating and protective glass into an organic solvent capable of dissolving paraffin for rinsing, and after the paraffin is dissolved, take out the diffraction grating. raster. The protection method of the diffraction grating provided by the present invention has simple process, readily available materials, low toxicity, and low cost, and can effectively protect the surface of the grating from damage during the cutting process, thereby realizing efficient and high-quality manufacture of the diffraction grating.

Description

technical field [0001] The present application relates to the technical field of diffraction grating protection, in particular to a method for protecting diffraction gratings during storage and transportation. Background technique [0002] Since the diffraction grating has a fine surface relief structure, it is very easy to be damaged. Therefore, during storage and transportation, not only the water vapor in the air, the saliva of the operator, and the sweat of the fingers will pollute the surface of the diffraction grating, but also the diffraction grating is subjected to external forces. Any extrusion situation will cause irreparable damage to the diffraction grating. Existing light barriers are usually packaged in boxes for storage and shipping. However, the surface of the grating is exposed to the air and is easily eroded by water vapor in the air. Therefore, it is very necessary to protect the surface of the diffraction grating first when storing and transporting it. ...
