As a   plano convex lenses supplier , I'd like to introduce it to you. What is the Plano Convex Lenses? Fused Silica Plano-Convex Lenses with 1064 nm Laser Line Antireflection V-Coating A plano convex lens is a lens that is flat on the one side and convex on the other. Plano convex lenses converge parallel light, correct the deflected light and convert point light sources into parallel light. When light enters from the convex surface of the plano convex lens, the light will converge to a point on the convex surface. When a point light source enters from the plane of the plano convex lens, the light will be turned into a parallel beam. The focal length of a plano convex lens can vary depending on wavelength. The Applications of Plano Convex Lenses Treatment of Hyperopia Hyperopia is the inability of the eyes to focus on nearby objects. In other words, you can see distant objects clearly, but you will encounter difficulties when looking at nearby objects. Therefore, in order to view

As an  Optical lenses Manufacturer , share it with you. When the light source illuminates the object under test, part of the scattered light diffuses into the object, part is absorbed by the object, and part penetrates the fruit. The degree to an object absorbs light is related to factors such as the nature of the object, the wavelength of the light , and the length of the propagation path. Some objects convert part of the absorbed light into fluorescence and delayed emission, etc. Through the detection of transmission spectrum and reflection spectrum, food defect detection, composition analysis, maturity and freshness analysis can be performed. Optical property detection technology measures the quality indicators of food, automatically classifies it, and distinguishes the overall quality level. Commonly used optical inspection instruments are photoelectric sorters and color sorters. The photoelectric sorting machine is a sorting device according to size. The color sorting machine uses

  Fused Silica Windows 1. High temperature resistance characteristics Quartz crystal has very high temperature resistance, its thermal expansion coefficient is very small and its chemical properties are also very stable. It can be made into various quartz instruments, quartz crucibles, quartz test tubes, quartz volumetric flasks, and is widely used in semiconductors, aerospace, photovoltaics, Infrared heating, chemical industry and other industries. 2. Excellent mechanical properties The mechanical properties of quartz crystals are better than those of glass and ceramics. Its accuracy is relatively high, and its volume can be made smaller and smaller. It is welcomed by many industries, especially in the 1970s, when quartz crystals were made into quartz watches by everyone Widely acclaimed. 3.has a piezoelectric effect When we cut the quartz crystal in a certain direction, it will generate an electric field or charge proportional to the stress when it is subjected to mechanical stress.
