An observation instrument includes an instrument shaft having a distal end and a proximal end, and an optical arrangement extending at least sectionally through the instrument shaft. The optical arrangement includes at least one optical component that is accommodated in a support shaft. The support shaft is arranged in the instrument shaft in an at least sectionally axially displaceable manner and is preloaded distally.

Observation instrument

An optical instrument () for minimally invasive surgery includes an instrument housing () for receiving optical elements, wherein the instrument housing () is sealed in fluid tight fashion by way of at least one end window () on the distal side and/or proximal side. The end window () is arranged in a window frame () that surrounds the end window () around the entire circumference thereof. The end windows () is able to be attached with little stress in the associated window frame () based on at least two portions () that project radially to the inside from the window frame (). The at least two portions () are formed on the inner circumferential surface of each window frame () facing the respective end window ().
