Optical glass dome:
Optical dome is composed of two parallel optical surfaces, normally we could control the parallel tolerance <2μm, optical dome mainly are hemisphere, hyper-hemisphere and customized designing, N-BK7 is a normal choice in visible application,the Spectral range (50% points) is from 285nm to 2800nm.is an important component in submersibles, it has wide-angle and can be protective of the deep-sea camera.The optical dome of Opticreate was produced by the optical technology of optical grinding and polishing.
