ABSTRACT:
A method for bonding a color separation filter to an image sensor. The method comprises the steps of dispensing an optical coupling composition on a preselected surface of at least one of the filter and sensor; bonding the filter to the sensor for creating a filter-sensor assembly, by using a predetermined amount of UV curable adhesive at an interface of the filter-sensor assembly; and, dispensing an epoxy along a periphery of the filter-sensor assembly, thereby encapsulating the optical coupling composition at the interface of the filter-sensor assembly.
