Dome
Domes can be used in pods and missiles. They are designed to protect electronic detectors and sensors from moving particles, water and corrosives. The optical domes provide front surface protection for detectors and sensors against moving particles such as sand, debris, and water while extending their viewing angles. They can be manufactured to specification from a variety of materials.
Key features:
-hemisphere / super hemisphere / special shape
-wide range of materials use
-small to big sizes
-two parallel curved surfaces available
