  • Removable optical assembly for a medical instrument
    Patent number: 7878972
    Abstract: An optical probe, for example, a medical endoscope, having a removable lens cell. In an embodiment, the optical probe has an elongated tube with a proximal portion terminating at a proximal end and a distal portion opposite the proximal portion terminating at a distal end. The elongated tube defines an axial lumen wherein a lens cell holder is disposed proximal the distal portion. The lens cell holder has an axial holder bore for at least partially containing the lens cell within and removably coupled with the holder bore.
    Type: Grant

  • Relay lens for an endoscope
    Patent number: 6088157
    Abstract: A relay lens for an endoscope or optical instrument is shown. The relay lens includes a first rod-type lens element having a first end and a second end. The first end defines a substantially spherical surface and the second end defines a convex surface. An optical element is positioned in axial alignment with and adjacent the first rod-type lens element. The optical element has a concave surface and a convex surface. The concave surface of the optical element is bonded to the convex surface of the second end of the first rod-type lens element forming a single bonded gap between the concave and convex surfaces. A second rod-type lens element having a first end and a second end, wherein each of the first end and second end defines a substantially spherical surface, is positioned in an axially aligned relationship with the first rod-type lens element and spaced from at least one of the first end of the first rod-type element and the concave surface of the optical element.
