Features

Scribed and Laminated Construction

Scribed and laminated soft coating construction is a commonly used construction for bandpass and edge filters. Optical filter components are coated onto separate substrate plates. These plates are then scribed to remove the film symmetrically around the required specified active film areas of the optical filters to be produced from the plate. The scribed plates are subsequently laminated together with a moisture resistant epoxy. A glass-epoxy-glass seal is formed in the scribed areas forming the best possible barrier to moisture penetration. Filters are cut through the scribed area to their finished size using diamond cutting tools. Additional moisture barriers may be applied to the cut filters if necessary to achieve extended life requirements.
