               Appeal No. 1997-1040                                                                                                   
               Application 08/175,893                                                                                                 


               (paper number 9), claims 1, 6 through 9 and 11 were amended.                                                           

                       The disclosed invention relates to a lens component, and to a method of making the same.  The                  

               lens component is comprised of two plastic lens elements cemented together or a plastic lens element                   

               and a glass lens element cemented together.  The interface between the plastic lens element and the                    

               cement is isolated by a glass coating on the plastic lens element.                                                     

                       Claims 1 and 10 are illustrative of the claimed invention, and they read as follows:                           

                       1.  A lens component comprising:                                                                               

                       a plastic lens element having an internal surface covered with a thin glass coating; and                       

                       another lens element cemented to said glass coating.                                                           



               10.  A method of cementing a plastic lens element to a glass lens element comprising:                                  

                       (i) coating said plastic lens element with a layer of thin glass coating; and                                  

                       (ii) cementing said glass coating of said plastic lens element to said glass lens element, thereby             
               cementing both elements to each other.                                                                                 
                                                                                                                                     

                       The references relied on by the examiner are:
