Abstract

Bei einem Handrefraktometer ist an einer Einstechspitze (11) eine Probemulde (7) angeordnet, so dass nach dem Eindringen der Einstechspitze (11) in eine Flüssigkeit beziehungsweise eine Frucht eine ausreichende Menge der Probeflüssigkeit in der Probemulde (7) verbleibt, um dort eine durch einen lichtdurchlässigen Körper begrenzte Messfläche (4) zu benetzen. Mittels einer Intensitätsmessung an einem an der Messfläche (4) reflektierten optischen Strahl kann die Brechzahl der benetzenden Flüssigkeit bestimmt werden.
