Abstract
A method of making an optical device comprises the steps of providing a body of vitreous material that is generally tubular along an axis. A portion of the body is molded with external mold structure for forming a bulbous portion when the interior of the tube is pressurized. An axial portion is cut from the bulbous portion to form a first coupling device with first and second axially oriented openings. This method can produce optical coupling devices with excellent optical quality in an economical manner.
