An optical connection apparatus is provided for removably connecting an electro-optical device, particularly a phototube transducer, to a transparent light-conducting material. The apparatus includes a transparent optical coupling disc which is bonded to an entrance window of the transducer with a transparent epoxy. The coupling disc has a threaded stud extending from a side of the disc opposite to the side which is bonded to the transducer. A hole is formed in the transparent material and a threaded insert is secured therein. The threaded stud extending from the disc/transducer combination is then mated with the threads of the hole insert. A layer of optical grease is placed between the disc and the transparent material, and the assembly is screwed together until the disc is flush against the surface of the transparent material.
