Abstract

An optical reflector, in particular for construction or geodetic surveying, has a reflective body (1) and a receptacle housing (3) for holding the reflective body (1). The reflective body (1) including transparent material has a transmission surface (5) and at least one unmetallized reflection surface (2). The receptacle housing (3) and the reflective body (1) held therein form a cavity. This is sealed water-tight from the environment of the reflector, for protecting the reflection surface (2). A structure for exchanging gas (4) is provided in the receptacle housing (3). A further development of the invention envisages detachable mounting of a component (17) on the reflector.
