Description
Winkelspiegel aus zwei versilberten Spiegelplatten, die auf einem Zwischengliede befestigt sind. In der englischen Patentschrift 1869 des Jahres 1913 ist vorgeschlagen, einen Winkelspiegel, der aus zwei auf einem Zwischengliede befestigten Spiegelplatten besteht, aus geschmolzenem oder ungeschmolzenem Quarz herzustellen. Der Verwirklichung dieses Gedankens steht der hohe Preis des Quarzes im Wege. Nach der Erfindung kann man dieses Hindernis beseitigen, indem man den Winkelspiegel aus Quarzgut, also aus zusammengeschmolzenem Sande, herstellt. Dem steht zunächst das Bedenken entgegen, daß Quarzgut wegen der überaus zahlreichen in ihm eingeschlossenen Luftblasen die Herstellung von optisch hochwertigen Spiegelflächen nicht erlaubt. Es ist jedoch der Erfindung gemäß der Ausweg vorhanden, den Winkelspiegel zwar aus Quarzgut herzustellen, die Spiegelplatten jedoch mit einem Überzug aus Quarz selbst zu überziehen. Ein solcher Überzug ist porenfrei herstellbar und erlaubt, wenn, in genügender Dicke angebracht, die Herstellung einwandfrei polierter Flächen, die dann versilbert werden. Ob man einen solchen Winkelspiegel aus einem Stück bestehen läßt oder ihn aus mehreren Teilen zusammensetzt, hängt von Erwägungen ab, die außerhalb des 'N'esens der Sache liegen.Corner mirror made of two silver-plated mirror plates on one Intermediate links are attached. In the English patent specification 1869 of 1913 is proposed an angle mirror, which consists of two fastened on an intermediate member Mirror plates are made from fused or unmelted quartz. The high price of quartz stands in the way of realizing this idea. To of the invention one can remove this obstacle by using the corner mirror from fused silica, i.e. from sand that has melted together. That stands first the misgivings that fused quartz because of the extremely numerous included in it Air bubbles The production of optically high-quality mirror surfaces is not allowed. However, according to the invention, there is a way out, although from the corner mirror Manufacture of quartz, but the mirror plates themselves with a coating of quartz to cover. Such a coating can be produced without pores and is permitted if, attached in sufficient thickness, the production of perfectly polished surfaces that then be silver-plated. Whether such a corner mirror can be made of one piece leaves it or composes it from several parts, depends on considerations outside of the 'n'esens of the matter.
