ABSTRACT:
A holder for precision working of optical lenses comprises a cylindrical base (4) designed as a dressing tool, a diaphragm holder (5) fastened thereto, an elastic diaphragm (6) attached air-tight thereto as well as a centric duct (22, 23) crossing the base (4) and the diaphragm holder (5) axially. The dressing tool (4) is preferably a cup-shaped tool to which a lens holder formed as a ring element (15) can be fastened in a capping manner. The lens holder (15) is provided with banking and/or supporting surfaces (21) as well as engaging elements (17) for holding a lens (19) to be worked; moreover, it may be provided with additional dressing elements (18). The dressing tool (4) and the lens holder (15) are combined to a combined tool K which can be fastened to a common rotating machine spindle (1). A polishing tool (13) is first dressed with the cup-shaped tool (4) whereupon the lens holder (15) is mounted and the lens (19) held by it is polished with the dressed polishing tool (13) against which the lens (19) is uniformly pressed by the diaphragm (6).
