Description

Autokollimationssystem Gegenstand der Erfindung ist ein Autokollimationssystem mit physikalischer Strahlenteilung, bei dem eine kreuzförmige Meßmarke vorgesehen: ist, die einerseits als Bezugssystem sichtbar ist, andererseits über einen Reflektor als Autokollimationsbild in die Ebene dieses Bezugssystems abgebildet wird.Autocollimation system The invention relates to an autocollimation system with physical beam splitting, in which a cross-shaped measuring mark is provided: which is visible on the one hand as a reference system and on the other hand via a reflector is mapped as an autocollimation image in the plane of this reference system.

In dem deutschen Patent 1099 213, welches sich mit derartigen Autokollimationssystemen befaßt, ist unter anderem bereits vorgeschlagen worden, die an der Meßmarke angebrachten Maßstabsmarkierungen so - z. B. mit anderer Lichtdurchlässigkeit als die Marke selbst - auszubilden, daß sie beim Autokollimationsbild nicht mehr oder nur schwach erkennbar sind. Hierbei ist der Vorschlag auf solche Autokollimationssysteme der eingangs geschilderten Art beschränkt, bei denen die beiden Meßmarken dem Betrachter hell auf dunklem Grund erscheinen.In the German patent 1099 213, which deals with such autocollimation systems concerned, has already been proposed, among other things, attached to the measuring mark Scale markings so - z. B. with a different light transmission than the brand itself - Train that they are no longer or only weakly recognizable in the autocollimation image are. The suggestion for such autocollimation systems is the one at the beginning described type, in which the two measuring marks are bright to the viewer appear on a dark background.

Der Erfindung liegt nun die Erkenntnis zugrunde, daß diesem Vorschlag durchaus allgemeinere Bedeutung zukommt. In diesem Sinne wird erfindungsgemäß vorgeschlagen, auch bei solchen Autokollimationssystemen der eingangs beschriebenen Art, bei denen die Meßmarke-in an sich bekannter Weisedunkel auf hellem Grund ausgebildet ist, die an der Meßmarke angebrachten Maßstabsmarkierungen so auszubilden, daß sie beim Autokollimationsbild nicht mehr oder nur noch schwach erkennbar sind. Auch in diesem Fall wirkt sich diese Maßnahme vorteilhaft aus: Das Gesichtsfeld wird übersichtlicher, und die Maßstabsablesung kann bequemer und genauer erfolgen.The invention is based on the knowledge that this proposal has a more general meaning. In this sense, it is proposed according to the invention, even with such autocollimation systems of the type described at the outset, in which the measuring mark - is formed in a known way dark on a light background, to form the scale markings attached to the measuring mark so that they are at Autocollimation image are no longer or only weakly recognizable. Also in this In this case, this measure has an advantageous effect: The field of vision becomes clearer, and the scale reading can be done more conveniently and accurately.
