Abstract
The present invention discloses a bonding collar for coupling optical components and methods for manufacturing the bonding collar and mounting the optical components to the bonding collar. The bonding collar is composed of a material having a thermal expansion coefficient comparable to that of the coupled optical components and is formed by a first socket into one end of a cylindrical blank and a square second socket in communication with the first socket so that when a GRIN lens is inserted in the first socket and a filter is placed in the second socket, the GRIN lens and filter will directly contact each other. Further, the manufacturing process ensures alignment between the two sockets. The filter and GRIN lens are bonded to the bonding collar by applying adhesive to the visible interfaces that the bonding collar forms with the GRIN lens and the filter.
