Abstract
For fixing an optical member such as a filter (12) to a support (10), more particularly for performing infrared observations on an artificial satellite, use is made of a device (18) having clamps (20) screwed into the support (10) and whose opposite ends respectively bear on the support and on the filter, a force distribution shim (26) being interposed between each clamp (20) and the filter (12). The tightening force is calibrated by means of one or more elastic washers (28) placed between the head of each fixing screw (22) and the corresponding clamp. Separating strips (24), preferably made from gold, are placed between the filter and the adjacent parts, to the right of shims (26).
