Hermetic Window Lids
Window lids allow light to be transmitted from or received by optical components within the hermetic package.
The transparent media is chosen to match the required wavelength to be transmitted. It is metalized and coated with customer specified anti-reflective coatings. We can manufacture window lids to your bespoke design. Typically a Ni / Au plated etched Kovar frame is used to support the window which is hermetically sealed often with Au/Sn solder preforms also manufactured by Hi-Rel.
These lids are available for integration in most sensor and other optoelectronic applications.
