ABSTRACT:
Methods and structures for reducing the moisture penetration in an optical device such as an isolator, collimator, filters, circulators, and the like. Methods can include placing an optical cover over the opening(s) of the housing of the optical device. The optical cover can be bonded by epoxy or metallic seal. A moisture prevention coating can be placed over the seal line between the optical cover and the housing to further enhance moisture prevention.
