Optical dome is our company's superior product. In the past, most of the fairings were infrared grade, which were mostly used in military products. With the development of military-civilian integration, especially in visible materials and ultraviolet , we have become one of the best optical components companies and have made technological breakthroughs, and we have obtained the patent certification of ultra-hemispheric processing technology.The dome is widely used in camera imaging, weather monitoring, navigation systems and so on. The radii of curvature of the two planes will not cause image distortion and light refraction. BRD Optical can provide different kinds of optical domes, like clear dome, UV dome and IR dome.
In the optical field, the application of a dome lens is mainly divided into two categories, one is military manufacturing and the other is ordinary optical systems.
Military manufacturing mainly refers to the infrared dome, mainly ZnSe and sapphire materials.
An optical system, mainly used for imaging and detection measurement system. It is mainly used for deep-sea imaging in imaging. The glass material can withstand sufficient water pressure and does not deform due to the acrylic material. Furthermore, the light transmittance of glass, the bubbles and stripes of the material itself, and the smoothness and hardness of the surface of the material itself make more deep-sea exploration keen to choose the glass material dome. Also used for atmospheric detection, pyranometer. The two almost parallel surfaces prevent the light from being significantly refracted when passing through the component, thereby ensuring that energy is not lost and improving the accuracy of the measurement.
First of all, this should be an optical component. Glass is more conducive to imaging, with better light transmission and stabilit. The surface of the glass is relatively hard and is not easily scratched. The surface of PMMA is easily scratched, which affects the imaging effect.
It is recommended to use a super hemisphere, the excess part can be glued with the assembly. In terms of cost, it is much cheaper than dome with flanges, and the sealing is also very good.
