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
Fluorescence filter is a key optical component used in life science instruments and biomedical applications. Its main function is to select and separate the excitation light and emission fluorescence characteristic spectral bands of substances in fluorescence inspection and analysis systems such as biology and medicine, and then observe them through a fluorescence microscope. Fluorescence filter generally consists of three combinations, namely excitation filter, dichroic mirror, and emission filter. Fluorescence excitation filter, also known as Excitation Filter in English
When the laser beam is perpendicular to the center of the mirror, the focusing quality is good. If the laser beam is tilted towards the mirror, the focusing quality will be greatly reduced, the focusing size will be significantly increased, and the optical power density will be greatly reduced, directly affecting the quality of power cutting. We carefully checked the optical path of the lens and determined the laser incidence positions at the four corners. Only by meeting the standards can we ensure the stability of the laser processing power density during the entire aperture operation. Secondly, use an optical path vertical calibrator, Zai
Fluorescent light sources are mainly used in fluorescence microscopes and are fundamental tools in cell biology. They consist of optical systems such as light sources, filters, lenses, etc. They use a certain wavelength of light to excite the specimen to emit fluorescence, and through the objective lens and eyepiece system, magnify and observe the fluorescence image of the specimen to achieve qualitative and quantitative research on the fluorescent sample. Excitation, filtering, imaging, quenching. The adjustment of fluorescence experiments essentially involves coordinating the above four factors to achieve the best results
The natural world is filled with electromagnetic waves, and the unit that distinguishes electromagnetic waves is wavelength. The wavelength range of visible light to the human eye is 380nm-780nm, with short wavelengths including ultraviolet, X-ray, and gamma rays, and long wavelengths including infrared, microwave, and radio waves. When electromagnetic waves are extracted at specific wavelengths, lasers are formed. The application of lasers in medical beauty mainly depends on their energy and penetration. Specific surface injuries can absorb lasers of specific wavelengths and destroy lesions through energy
