The optical dome is not only an innovation in the field of optics but also an indispensable protective barrier for numerous precision devices. With its unique hemispherical or custom shapes, the optical dome serves as a bridge connecting the external environment with precision optical systems, while also playing the role of a solid guardian.
As the name implies, an optical dome is an optical window with strong curvature. Infrared dome is made of high-quality optical glass or infrared materials, such as BK7, fused silica, and sapphire, which ensure the lossless transmission of light. The exquisite design of the optical dome can withstand harsh environments that might harm the internal precision equipment. Whether it is the LIDAR sensors on airplanes or underwater cameras in deep seas, the optical dome ensures stable operation of the equipment under extreme conditions with its excellent protective performance.
The optical dome boasts excellent impact resistance, scratch resistance, and high-temperature resistance. More uniquely, the optical dome is not just a robust defensive line but also a precise optical component. It can evenly distribute light, reduce beam deflection, and enhance the performance of anti-reflective coatings, keeping the light in optimal condition during transmission. This design not only protects the internal equipment but also enhances the overall performance of the optical system, making observational results more accurate and clear.
Optical dome is primarily used to protect sensitive systems. For instance, LIDAR optical sensors installed on airplanes must be protected by a very sturdy dome to withstand the high-speed impacts from sand and even birds. Similarly, dome cameras for submarines and underwater cameras and video systems must endure high pressure.
With Cngeir infrared optical products, Due to the priority of protective functions, the optical dome must make some compromises concerning optical performance. Sometimes harsh operating conditions may prevent the outer surface from maintaining very high optical quality. There are also other coatings used for optical domes, such as those with particularly high durability, anti-reflective coatings, infrared filter coatings, and metallized coatings. Some optical domes have special mechanical properties to achieve precise installation and sealing.
