Abstract
A package for an optical assembly of a type that uses bulk optics in an optical path will require environmental protection from contaminants. It is common to construct a substantially hermetically sealed package to provide environmental protection for the optical assembly but such hermetically sealed packages are expensive to construct and are not completely reliable. Consequently, a package is provided for an optical assembly with the bulk optics encapsulated by a silicone encapsulant and encased within an epoxy layer and supported by a substrate base. The package for the optical assembly thus provides the bulk optics with the required environmental protection from contaminants.
