Claim 0:
1. An observation instrument comprising:
an instrument shaft having a distal end and a proximal end;
a distal end configuration fixedly attached to the distal end of the instrument shaft, the distal end configuration comprising a distal end element;
a support shaft at least sectionally axially slidably supported in the instrument shaft;
an optical arrangement extending at least in sections through the support shaft and supported by the support shaft, the optical arrangement comprising an optical component supported by and relative to the support shaft;
a support shaft biasing device, biasing the support shaft toward the distal end of the instrument shaft, the support shaft biasing device being arranged at a proximal position, adjacent to the proximal end of the instrument shaft, and acting on and adjusting the support shaft and not acting on and not adjusting the optical arrangement at the proximal position; and
an optical arrangement biasing device acting on the optical arrangement and biasing the optical arrangement toward the distal end of the instrument shaft relative to the support shaft, the support shaft biasing device and the optical arrangement biasing device cooperating to maintain abutting contact of at least one of the support shaft with the distal end configuration and the optical arrangement with the distal end configuration to maintain the optical component immediately adjacent to the distal end configuration.
