Infrared imaging technology can be divided into active infrared imaging and passive infrared imaging. Passive infrared imaging uses the infrared radiation emitted by the object to capture the image of the object. Active infrared imaging irradiates an object with an infrared radiation source and using the reflected infrared radiation to capture the image of the object. Infrared intrusion detectors are often used for civil security and military security. The p assive infrared intrusion  detection  system The passive infrared intrusion detection system is mainly composed of an optical system and a pyroelectric sensor. The optical system is usually composed of multiple sets of  optical lenses  and  mirrors  to form a flabelliform protective area overlooking downwards. While opening the fan-shaped viewing angle, it also takes into account target detection in far, middle and near areas. In order to detect the infrared moving target, the thermal energy radiation of the moving target needs to

As a   Silicon Domes Manufacturer , share with you. Optical glass can change the direction of light propagation. Optical glass is widely used in many modern high-tech industries such as aerospace, information, microelectronics, surveying and mapping with its unique characteristics of high temperature resistance, low expansion coefficient, high mechanical strength, and good chemical properties. Optical glass is widely used in lenses and prisms of optical instruments. Optical glass must meet the requirements of light imaging, so the quality of optical glass is also very high. Glass Optical Domes Qualified optical glass must meet the following requirements: 1. The optical constants of the optical glass and the same batch of glass must be consistent. The optical glass has a specified standard refractive index value for different wavelengths of light, which serves as the basis for the optical designer to design the optical system. Therefore, the optical constants of the optical glass produc

  Our  optical domes  are widely used in solar energy measuring instrument, underwater camera and high-pressure window of submersible. It provides long-term protection for measuring instruments in natural and expose d environment. The stability of our material protects the instruments from erosion of natural environment. It can also work at depth of 5000m under the water. Because of the stability of dome, it can greatly protect the proper functioning of underwater camera and provide high light transmittance with a 180 °  field of view, which is one of the most important elements for deep-sea detection. During the last few years, we’ve delivered more than 25,000  dome lenses . Through years of accumulation, we possess many kinds of ready-made tools and stocks sized from 24mm to 125mm. We can ensure  the fastest delivery date, the best quality and the most optimal price whenever you need.
