TL;DR: In this paper, a colored absorber with a TiNxOy absorbing layer and a TiO2/Si3N4/SiO2 dielectric stack is designed and can be fabricated with only two targets, Ti and Si, by using reactive magnetron sputtering.

TL;DR: In this article, an optical detection device for defects of coated glass film is presented, wherein one side of a detected sample is made into a 45-degree lead angle; the light transmitted by a laser light source is expanded by an expander lens and then parallelly comes in from the side surface of the detected sample; and the light is subjected to total internal reflection in a glass air interface and a film-air interface.

TL;DR: In this paper, a method for preparing a vanadium dioxide film was proposed, in which metal vanadium or low-valence vanadium oxide film is annealed in oxygen and vacuum to obtain a phase-transition vanadium odometry film; the most proper oxygen partial pressure, the annealing temperature and the anning time are selected according to the type and thickness of the low value of the vanadium oxides to obtain an excellent performance, wherein the infrared regulation rate at 2,400nm can be 58 percent, and the visible light transmittance can

TL;DR: In this paper, a blue light filter film for visible light communication is presented, which is structurally characterized in that a wide-pass band interference cutoff filter film, a high reflection film and an antireflection film are arranged on a substrate sequentially.
