Description

Testfigur für den Rotgrünausgleich bei der Brillenbestimmung. ------------------------------------------------------------- Es ist bekannt, für den genauen Abgleich der Akkommodation bei der Brillenanpassung dem einen Auge einen grünen, dem anderen einen roten Test darzubieten. Es ist auch bekannt, Teile des grünen oder roten Testes jeweils auch dem anderen Auge zu zeigen. Zu diesem Zweck benutzt man vier aneinanderliegende Quadrate oder Kreissektoren, von denen je zwei benachbarte rote und grüne Strahlung aussenden, und je zwei gegenüberliegende Polarisatoren gleicher Schwingungsrichtung enthalten.Test figure for the red-green balance when determining the glasses. -------------------------------------------------- ----------- It is known to present a green test to one eye and a red test to the other for the precise comparison of accommodation when fitting glasses. It is also known to show parts of the green or red test to the other eye. For this purpose, four adjacent squares or sectors of a circle are used, two of which each emit adjacent red and green radiation, and each contain two opposing polarizers with the same direction of oscillation.

Die Erfindung benutzt eine undurchlässige Platte, beispielsweise ein Blech oder eine in übrigen geschwärzte fotografische Platte mit einer runden oder quadratischen Öffnung, die in vier Sektoren oder kleine Quadrate so geteilt ist, daß je zwei benachbarte grünes bezw. rotes Licht hindurchlassen und je zwei einander gegenüberliegende polarisiertes Licht gleiche Schwingungsrichtung. Die Erfindung besteht darin, daß diese Figur konzentrisch von einem weißes unpolarisiertes Licht hindurchlassenden schmalen Kreisring umgeben ist, der einen Fusionsreiz bietet.The invention uses an impermeable plate such as a Sheet metal or a photographic plate blackened in the rest with a round or square opening divided into four sectors or small squares so that two neighboring green respectively. let red light through and two each to each other opposite polarized light in the same direction of oscillation. The invention is that this figure is concentric by a white unpolarized light passing through narrow circular ring is surrounded, which offers a fusion stimulus.

Weiterhin gehört es zur Erfindung, daß die gesamte Testplatte um ihren Mittelpunkt in dem üetrachtungs-oder : Pwojektionsgerät nach Belieben drehbar ist. Ihre Felder können Sehzeichen tragen, etwa undurchsichtige Liarken in Buchstaben-oder Zahlenform. Furthermore, it belongs to the invention that the entire test plate around its center in the viewing or projection device can be rotated at will is. Your fields can have optotypes, such as opaque Liarken in letters or Number form.

In der Figur ist ein Bespiel gemäß der Erfindung wiedergegeben worden. In the figure, an example has been shown according to the invention.

Die durchsichtige Platte 1 trägt in der liitte eine kreisförmige Öffnung mit den beiden grünen Sektoren 12 und 13 und den roten Sektoren 22 und 23, von denen die Sektoren 12 und 22 polarisiertes Licht einer Schwingungsrichtung, die Sektoren 13 und 23 Licht der dazu senkrechten Richtung hindurchlassen. Diese Figur ist von dem konzentrischen lichtdurchlässigen Kreisring 4 umgeben. Die Sektoren enthalten undurchsichtige Ziffern.The transparent plate 1 carries a circular opening in the liitte with the two green sectors 12 and 13 and the red sectors 22 and 23 of which the sectors 12 and 22 polarized light of one direction of oscillation, the sectors 13 and 23 allow light to pass through in the direction perpendicular thereto. This figure is from the concentric translucent circular ring 4 surrounded. The sectors included opaque digits.
