Problems solved by technology

For example, reflected light from a water surface, glass surface or metal surface will contain polarized light, and this polarized reflected light will cause glare, making the observer visually uncomfortable and thus unable to see objects clearly
[0004] Since most of the polarized light that causes glare is X-type polarized light, in order to solve this problem, it is known that polymer materials are drawn into filaments and arranged in a direction to eliminate X-type polarized light to reduce glare. However, due to the lack of free electrons in polymer materials, the efficiency of eliminating electric field vibrations is poor, and a certain thickness must be used to achieve the effect of reducing glare. However, the increase in thickness will lead to a serious decrease in light transmittance, making this material more Difficult to apply to optical products

Abstract

The invention provides an optical element which comprises a substrate and an anti-glare layer, wherein the substrate has a surface, and light reflected by a smooth plane is incident on the surface of the substrate; and the anti-glare layer comprises a plurality of carbon nanotubes which are parallelly arranged on the surface of the substrate, and the length extension directions of the carbon nanotubes are parallel to a polarization direction of the light.

Description

technical field [0001] The invention relates to an optical device and an optical element thereof, in particular to an optical device based on carbon nanotubes and an optical element thereof. Background technique [0002] Light is a kind of electromagnetic wave, which is formed by the vibration of alternating electric field and magnetic field perpendicular to the direction of light propagation. The wave whose vibration direction is perpendicular to the direction of propagation is also called transverse wave. The vibration of the transverse wave is polar. Generally speaking, the polarity of light refers to the vibration direction of the light wave in the electric field. If the vibration direction of the light wave is asymmetric to the direction of light propagation, it is called polarized light. [0003] Generally, the vibration of natural light in all directions is uniformly distributed, which belongs to unpolarized light. However, when unpolarized light is incident on a smoo...
