A light transmission system includes a laser, an optical fiber and a transfer lens. The fiber optic transfer for transfers light emitted by the laser into the optical fiber. The transfer lens includes a hyperbolic collimating surface for receiving and collimating light originating from the laser. The transfer lens also includes an output lens surface shaped so that light reflected from the end of the optical filter is not focused at a location at which the light is emitted by the laser. Additionally, in various preferred embodiments light launched into the optical fiber avoids index anomalies on the axis of the optical fiber and at the core-cladding interface.
