Abstract

The invention belongs to the technical field of night vision piece preparation, and particularly relates to a night vision piece and a preparation method thereof. The night vision piece comprises a base material, a nano linear metal and an additive, wherein the additive comprises one or a mixture of cyanine, phthalocyanine, thiodiene, a metal complex, quinones, azo and quinolines. According to theinvention, various materials with different visible light and infrared light absorption spectral lines are doped; the night vision piece can change the visible spectrum of the LED to meet the color coordinate requirement of the night vision compatibility requirement, and the night vision piece can absorb the near infrared radiation emitted by the LED light source and generated by the ambient background light to meet the radiance requirement of the night vision compatibility requirement.

Description

technical field [0001] The invention belongs to the technical field of night vision film preparation, and in particular relates to a series of night vision filters with visible light and infrared light absorption functions, which can make LED light sources meet night vision compatibility requirements, and a preparation method thereof. Background technique [0002] In the Background of the Invention, the disclosed information is only intended to increase the understanding of the general background of the present invention, and is not necessarily to be regarded as an acknowledgment or in any form to imply that the information constitutes the prior art already known to those skilled in the art. [0003] Night vision compatible technology refers to the technology that eliminates the infrared radiation emitted by the light source system that interferes with the work of the night vision device through certain methods, and ensures that the night vision imaging system can work normal...
