Optical device assembly having a cavity that is sealed to be moisture-resistant

摘要

Described herein is an optical device assembly. The optical device includes a housing with a moisture-resistant sealed cylindrical cavity (125) in which first and second optical surfaces (116, 132) are optically coupled, the first optical surface being disposed on a first optical element (122) that is within a first end of the cylindrical cavity and the second optical surface being disposed on a second optical element (123) that is within a second end of the cylindrical cavity that is opposite the first end.
