Abstract

An optical coupler for coupling to a rotating catheter has a housing with a rotatable distal face and a stationary proximal face. The distal face has an eccentric port and a central port. A lens is disposed inside the housing to intercept a rotating collection beam emerging from the eccentric port and to re-direct the collection beam to a focus proximal to the lens as the collection beam rotates. A beam re-director disposed between the lens and the distal face is oriented to direct a delivery beam toward the central port.

Claims (4)

1 . An optical coupler comprising:

a housing with a rotatable distal face and a stationary proximal face, the distal face having an eccentric port and a central port;

a lens disposed inside the housing to intercept a rotating collection beam emerging from the eccentric port and to re-direct the collection beam to a focus proximal to the lens as the collection beam rotates; and

a beam re-director disposed between the lens and the distal face, the beam re-director being oriented to direct a delivery beam toward the central port.
