Abstract
In a first variation, the novel optical unit (10) comprises several optical elements (14.1, 14.2, 14.3, 14.4, 14.5), and an integrally produced support structure (12) with element supports (16.1, 16.2, 16.3, 16.4, 16.5) for each of the optical elements (14.1, 14.2, 14.3, 14.4, 14.5). At least one of the element supports (16.1, 16.2, 16.3, 16.4, 16.5) is formed by a simply connected body, i.e. a linear support (16.4) or a plate (16.1, 16.2, 16.3, 16.5), or shell. The dimensions of this element support are matched to the optical element (14.1, 14.2, 14.3, 14.4, 14.5), wherein at least a portion of the element supports (16.1, 16.2, 16.3, 16.4, 16.5) is partially free along their rim. In a second variation the optical unit (10) comprises at least one optical element (14) and an integrally produced element support (16) made of the same material, preferably Zerodur.RTM.. The optical element (14) is preferably fastened directly on the element support (16) by gluing. The optical unit (10) having the characteristics of the first and/or second variation is suitable for use as a component of an apparatus intended for employment in space, wherein the receiving structure (12) is fastened on the apparatus at least approximately isostatically.
