Abstract

Die Erfindung bezieht sich auf eine Vorrichtung zum Bestimmen des Randwinkels (η) eines auf einer Unterlage (1) aufgebrachten Tropfens (2) mit einer Dosiereinrichtung (3) zum definierten Aufbringen des Tropfens (2) und einer Kamera (4) mit zugeordneter Auswerteeinrichtung und Anzeigeeinheit (5). Ein kompakter, leicht handhabbarer Aufbau wird dadurch erzielt, dass die Vorrichtung als Handgerät mit einem die Dosiereinrichtung (3), eine Beleuchtungseinrichtung (6), die Kamera (4), die Auswerteeinrichtung und die Anzeigeeinheit (5) haltenden, auf der Unterlage (1) aufsetzbaren Tragegerüst oder Gehäuse ausgebildet ist.
