Abstract: An optical window which has an excellent transmission characteristic over a wide range from the infrared region to the vacuum ultraviolet region, can be attached to an ultra-high vacuum apparatus, and has excellent properties enough to withstand baking. A method of manufacturing the optical window comprising the steps of forming an optical window which is made of at least diamond as a window material, a flange for a vacuum apparatus, a joint frame for joining the diamond to the flange, and a joining material of specified properties for joining the joint frame to the diamond, and a diamond plate, fitting the joint frame to the flange, and fitting the diamond plate to the joint frame through the joining material. The effect is further enhanced by suitably specifying the shape, material and so forth of the joint frame.

Abstract: PROBLEM TO BE SOLVED: To provide the optical window with superior characteristics, which has superior transmission characteristics over a wide range of the infrared to vacuum ultraviolet regions and can be fitted to an ultrahigh vacuum device and is resistant to baking, and its manufacturing method. SOLUTION: The manufacturing process comprises a process of manufacturing an optical window consisting of at least diamond 31 as a window material, a flange 22 for the vacuum device, a bonded frame 21 for joining the diamond 31 with the flange 22, and a bonding material 32 made of a specific material for bonding the bonded frame 21 with the diamond 31 and the diamond plate 31, a process of fitting the bonded frame 21 to the flange 22, and a process of fitting the diamond plate 31 to the bonded frame 21 through the bonding material 31. The effect further increases by properly determining the shape, material, etc., of the bonded frame 21.
