BRD Optical can provide the Hyper hemisphere Dome lens, not only a glass dome, but also a dome with flange, is widely used with all kinds of cameras such as 
CCTV, ROVs, etc. The flanges are easier to install. Of course it retains all its optical properties.
In the current market, more are acrylic products, After all, acrylic material is easier to form, but its optical properties are limited, secondly, its surface is easy to be engraved, which will greatly reduce the imaging effect.
It is harder for glass to form and make useful optical elements, Through repeated design and experiment, BRD optical has successfully produced autumn optical dome with flange.
