Piezo earphones ore radio circuit, when receiving radio, use C2 to tune, and the antenna is connected to A2, which can improve the selectivity.
Anti-Reflection Coating Product
Anti-reflection coating, also known as anti-reflection coating, is an optical thin film deposited on the surface of optical elements through ion-assisted evaporation to reduce surface reflection and increase the transmittance of optical elements. The working band can be from the near-ultraviolet region to the infrared region. According to the working band range, it is divided into single wavelength, multi-wavelength and broadband antireflection coatings. The most widely used ones are visible light antireflection coatings and single point antireflection coatings.
Anti-reflection film is the most widely used optical film with the largest output. Therefore, it is still an important research topic in optical film technology. The focus of research is to find new materials, design new film systems, improve deposition processes, and make It uses the least number of layers, the simplest and most stable process, to obtain the highest possible yield and achieve the most ideal effect.
In optical instruments, the reflection on the surface of the optical element not only affects the light energy of the optical element; moreover, these reflected light will also form stray light in the instrument, which affects the imaging quality of the optical instrument. In order to solve these problems, a certain thickness of single-layer or multi-layer film is usually plated on the surface of the optical element. The purpose is to reduce the reflected light on the surface of the element. Such a film is called an optical antireflection film (or antireflection film). The antireflection coating produced by Gengxu Optoelectronics is mainly used in LED display screens, touch screens, LCD projection systems, glass coatings, instrument windows, fingerprint analyzer windows, monitor protection mirrors, antique frame windows, high-end watch windows, eye lenses , Silk screen optical glass products, etc.
