Summary:PROBLEM TO BE SOLVED: To provide an endoscope optics with enlarged structure possibility at a low cost, for which PPS or PPSU plastic being extremely stable relative to temperature is used for a hermetic housing. SOLUTION: The rigid endoscope optics (1) including the housing consisting of several housing parts (5, 8, 9, 6, 16) which hermetically encloses optic elements (3, 2, 4) and which is fitted with a hermetic connection (13, 14;7, 15) between two housing parts (9, 8; 9, 16) is characterized in that one (9) of the connected housing parts is made of PPS (polyphenylenesulfide) plastic or of PPSU (polyphenylsulfone) plastic, and the other (8, 16) connected housing part is made of PPS, PPSU or glass, the housing parts (8, 9, 16) being fitted with a metal coating (7, 13, 14, 15) at the connection site (13, 14; 7, 15) and are soldered to one another.
