Abstract
A deflection prism assembly for an endoscope having a lateral viewing direction. The deflection prism assembly including: a prism holder; and a deflection prism which is received in the prism holder. The deflection prism is formed of a glass. The prism holder includes a reception component and an adjustment component, where the reception component is formed of a ceramic and the adjustment component is formed of a metal. The deflection prism is attached to the reception component and the adjustment component provides a stop for the deflection prism in an axial direction.

A deflection prism assembly for an endoscope having a lateral viewing direction, the deflection prism assembly comprising:
- a prism holder;
- and
- a deflection prism which is received in the prism holder;
- wherein the deflection prism is formed of a glass;
- the prism holder comprises a reception component and an adjustment component, the reception component being formed of a ceramic and the adjustment component being formed of a metal;
- the deflection prism is attached to the reception component and the adjustment component provides a stop for the deflection prism in an axial direction;
- at least a portion of the adjustment component is arranged concentrically within the reception component in a radial direction relative to a central axis of the deflection prism;
- the deflection prism comprises a light outlet face and an opposite light inlet face arranged diagonally relative to the light outlet face, a lateral face extending between the light outlet face and the light inlet face, wherein the prism holder is arranged relative to the deflection prism such that the prism holder is circumferentially discontinuous on the lateral face of the deflection prism;
- and
- the prism holder surrounds the lateral face of the deflection prism in a first region, wherein a second region of the deflection prism radially opposite the first region is not surrounded by the prism holder.
