Problems solved by technology

[0003] However, nowadays, most diffuse reflectors can work in a small range of wavelengths, and most of them can only work in the range of visible light sources, and the reflectivity is single, the stability of the material is poor, and the diffuse reflector surface is easy to yellow and fall off, so it is not easy to store. In some conditions Harsh field ring mirrors will affect their performance, thereby affecting the efficiency of measurement work

Embodiment Construction

[0029] refer to figure 1 , a manufacturing method of a diffuse reflector, comprising the following steps:

[0030] Step a1, pretreating the substrate;

[0031] Step a2, according to different reflectance ratio spraying material proportioning;

[0032] Step a3, controlling the amount of spraying and spraying time according to different reflectances to spray on the substrate surface to form a diffuse reflection surface;

[0033] Step a4, curing the diffuse reflection surface.

[0034] refer to image 3 , image 3 It is a graph of the relationship between wavelength and reflectance of spraying materials with different ratios; diffuse reflectors with different reflectances are used for different functional purposes, and the ratios are made according to actual requirements; different ratios of sprayed materials will affect the reflection of the diffuse reflection layer Ratio, the specific available reflectance is 2% to 99%. At the same time, due to the different proportions o...

Abstract

The invention discloses a manufacturing method of a diffuse reflection plate. The method comprises: preprocessing a substrate; carrying out matching of spraying materials based on different reflectance ratios; controlling a spraying amount and spraying time based on different reflectance ratios and carrying out spraying on the substrate surface to form a diffuse reflection surface; and solidifyingthe diffuse reflection surface. The diffuse reflection plate made based on the manufacturing method has the flat spectrum in an ultraviolet-visible-near-infrared spectrum region and has characteristics of high thermal stability and chemical stability, great easiness in cleaning, high stability, high reflectivity, good high-and-low-temperature-resistant performance, and good radiation-resistant performance, so that the diffuse reflection plate is suitable for experiment and field applications in long-term-exposed or harsh environment.

Description

technical field [0001] The invention relates to the technical field of physical optical materials, in particular to a diffuse reflection plate and a manufacturing method thereof. Background technique [0002] At present, spectral calibration is an indispensable step in the measurement of spectral instruments. Diffuse reflection plate is an important optical device in the application of spectral calibration. The quality of its reflectivity directly affects the accuracy of spectral instrument measurement, thus affecting the instrument Accuracy of acquired data on a measured object. With the development of science and technology, spectroscopic instruments can be quickly analyzed and applied to many industries such as machinery manufacturing and biotechnology, and have rapid development in target positioning, mineral exploration, and ecosystem research. For example, the diffuse reflector can be used to calibrate the UAV airborne camera in the field environment. After the calibr...
