Solderable Edge Metalizations

Brysen’s solderable edge coatings can be applied to visible and IR windows, providing a durable hermetic seal to optical systems. Brysen has photolithographic capabilities to apply patterns on filters. Windows can be bonded or soldered into opto-mechanical assemblies. Unique tooling is engineered and fabricated to meet part-specific dimensions and tolerancing.

Brysen’s solderable edge metalizations are a proprietary multilayer metal coating for hermetically sealing optical windows and filters. Substrates include optical glasses, Germanium, Sapphire, Zinc Sulfide, Zinc Selenide, Calcium Fluoride and many others. A wide variety of substrate shapes and sizes can be edge coated. Substrates can be coated individually, or patterned in an array for post-deposition dicing or core cutting. These films have excellent adhesion and pass solderability, high temperature and cryogenic testing. Available coating profiles include surface periphery, surface edge  and wrap around .
