Polarized light is a type of light wave with specific vibration direction, which can vibrate in a specific plane or rotate in a specific way. According to the different polarization states, light waves can be divided into linearly polarized light, circularly polarized light, and elliptically polarized light. This article will focus on introducing the basic concepts, generation methods, and main differences between linearly polarized light and circularly polarized light. Linear polarized light, also known as plane polarized light, refers to the vibration direction of light waves always being fixed

Dear employees and respected customers of Ruicheng Optoelectronics, the following is our company's 2020 Spring Festival holiday schedule. Please be informed:
As one of the the Four Great Inventions of the twentieth century, laser technology, along with computer, semiconductor and atomic energy technology, has been widely used in many industries. However, when it comes to laser, most people can think of its application in mechanical processing. In fact, in addition to industrial cutting, welding, and medical beauty applications Laser has many other uses, such as in cooling. The concept of laser cooling was first proposed by Soviet scholars in 1962
Researchers have discovered a natural hyperbolic material with extreme optical properties called in-plane hyperbolic. This discovery is likely to make it possible for infrared optical components to be replaced. Hyperbolic materials have high reflection of light along a certain axis and reflect light along a vertical axis, usually with one axis within the material plane and the other axis outside of that plane. Dual axis materials on the same plane can be used to make optical components, such as ultra-thin waveplates, which can change the polarization of incident light
At present, most water quality tests require the detection of total nitrogen content. There are various types of nitrogen in water, including organic nitrogen-containing compounds, nitrite nitrogen, inorganic ammonium salts, nitrate nitrogen, and dissolved ammonia, which can be converted into each other through biochemical reactions. Total nitrogen refers to the total amount of soluble nitrogen and nitrogen content in suspended particles. When the nitrogen and phosphorus content in surface water is too high, the water becomes eutrophic, leading to the proliferation of microorganisms, vigorous growth of phytoplankton, and deterioration of water quality
In fact, nowadays digital cameras have UV/IR Cut filters in front of their image sensors. UV lenses are used in new digital cameras and no longer have their original optical correction function, which can block UV and infrared rays that affect the image. Therefore, adding UV (Ultraviolet) filters in front of the lens is actually a repetition, and generally does not significantly improve the image effect. However, for many people, it is still a useful tool
Today, let's take a look at the infrared imaging technology currently used in the field of optics. Essentially, infrared light is caused by the heating of matter. Infrared thermal imaging technology is a passive infrared night vision technology that emits infrared radiation of different wavelengths based on the property that all temperatures of an object are above absolute zero. This infrared radiation contains the characteristic information of the object. The thermal imager detects the infrared radiation emitted by the object, generates real-time images, and provides a thermal image of the scene, capturing human flesh
