Abstract:
1. An optical system for emitting and/or receiving light, comprising: a catheter having a distal end; a fiber optic probe located at the distal end of the catheter, said fiber optic probe comprising an outer housing assembly having a tubular section with a portion open to form a window, and a cap section installed within the window; and a lens structure installed in the fiber optic probe within an optical port adjacent to the cap section to accommodate transmission of a beam, wherein the lens structure couples light to and/or from an optical fiber of the optical system, the lens structure being formed in composite wafer material that comprises a first layer, a second layer, and an interlayer between the first layer and the second layer, a refractive lens being formed in the first layer and an optical port being formed as a hole through a backside of the composite wafer material, through the second layer and along an optical axis of the refractive lens.
