石英玻璃 石英玻璃是硅的单组分非晶态材料，是一种非常优秀的特种工业技术玻璃。它的微观结构是由硅的四面体结构单元组成的简单态。由于si-o化学键能大，结构紧密，石英玻璃具有独特的性能，特别是透明性。石英玻璃在紫外到红外的连续波长范围内具有优异的光学性能和透射率。 一、耐高温。石英玻璃的软化点温度约为
In daily life, handicrafts and products with unique appearances and patterns can be seen everywhere, using materials such as steel, wood, plastic, glass, etc. These pleasing spoons do not require laser cutting. Laser cutting has the advantages of fast speed, narrow incision, and smooth edges. Due to the high price of cutting heads, companies often add laser protective lenses. On the other hand, while protecting the cutting head, there are also hidden dangers in protecting the lens. During the production process of laser cutting machine, laser energy
All optical components are precise, especially the filter, which is the core component of all optical application systems. Once a problem occurs, it can cause the entire optical system to malfunction. Therefore, when using and maintaining the filter, the following precautions should be taken as much as possible: 1. When the acid and salt on the glass surface are easily corroded, if the filter is directly touched by hand, it will leave marks on it. If not erased for a long time, it may become a permanent light spot, affecting
Interference film is a typical short wave filter, which has been used as an anti reflection film for lenses in periscopes and binoculars since World War II. Infrared filters, as indispensable optical components for military use, are widely used in missile automatic guidance, infrared communication systems, aircraft beacons, and land and sea infrared detection and tracking systems. Since modern times, with the further development of optical communication technology and the gradual industrialization of display technology, the development speed of optical thin films has accelerated
Colored glass filters utilize the intrinsic absorption of colored ions in colored optical glass to affect the spectrum, resulting in different colors. It can accurately select the small range of light waves that it wants to pass through, while absorbing other unwanted bands. Also known as optical filter glass, it is mainly used to make filters for observation, photography, infrared and other instruments to improve instrument visibility or meet certain special requirements. It can also be used to make colored glasses. According to the different types of coloring agents, they can be classified
The principle of fluorescence spectroscopy is applied in the field of analysis, and fluorescence filters can be used for real-time observation, qualitative identification, and quantitative analysis of biochemical activity. Fluorescence spectroscopy technology has been widely used in the fields of biology and analysis due to its high sensitivity, good specificity, and easy operation. Most fluorescent instruments, including most fluorescence microscopes, are typically of the fluorescent filter type. A typical system consists of three filters: excitation filter (excitation), dual color beam splitter（
CCD and CMOS sensors are currently the most commonly used digital image sensors. Both CCD and CMOS use photosensitive elements as the basic means of image acquisition. The core of CCD and CMOS photosensitive components is a photodiode, which can generate output current and current intensity after receiving light, corresponding to the intensity of light. CCD Charge Coupled Device (ChargeCoupLEDDevICe) is a highly sensitive semiconductor material

Filters are generally called filters in photography and astronomical observations, abbreviated as UHC filters. UHC filters are the abbreviation for Ultra High Contrast Filters in English and belong to the broadband filters in the astronomical filter series. UHC selectively blocks certain harmful wavelengths of light, especially artificial light (including mercury and sodium) and natural sky glow, allowing useful light emitted by nebulae to pass through efficiently. This filter
Laser protective lenses, also known as laser window lenses, laser window lenses, etc., are mainly used in laser equipment and can be divided into YAG fiber laser protective lenses and CO2 laser protective lenses (zinc selenide protective lenses). Ruicheng Optoelectronics exclusively launches YAG fiber laser protective lenses that can withstand 21000W laser power and zinc selenide protective lenses that have comparable performance to imported CO2 laser protective lenses. The importance of laser protective lenses in laser equipment: Currently,
