23 Mar 2020 Glass domes are widely used for commercial applications which require protective boundary between different environments; domes perform as windows, providing protection to electronic sensors or detectors without sacrificing field of view.
Composed of two parallel optical surfaces, domes have no optical effect on design optical path. In lead element in an optical system, a dome is exposed to the environment, N-BK7 is good choice for visible to near infrared lead applications, which will withstand wind and rain erosion.
Typically in single-use defense applications and ocean exploration. Shapes can vary from hemispheric to custom size with coatings. |
