Abstract

The present invention, among other things, relates to a front-lens attachment (20) for an optical observation device (10), in particular for a microscope. The front-lens attachment (20) has a retaining element (38) that has a retaining element (32), on which at least one lens element (33, 34) is disposed. Further, it provides a positioning device (21) for positioning the retaining element (32) and the at least one lens element (33, 34) disposed thereon, relative to the optical observation device (10), whereby retaining device (32) is disposed on positioning device (21). Finally, a fastening means (35) for fastening the retaining device (38) to the front-lens attachment (20) is provided. In order to be able to provide such a front-lens attachment (20) in a structurally simple and cost-effective manner, it is provided, for example, that positioning device (21) has at least two positioning components (22, 28), which are joined together via a joint (31).
