Title (EN) MULTIPLE WAY PRISM FOR B4-STANDARD
(FR) PRISME À TRAJETS MULTIPLES POUR NORME B4
(DE) MEHRWEGE-PRISMA FÜR B4-NORM
Abstract:
(EN) The invention relates to an optical arrangement (200) comprising a stacked structure (201) having at least three prisms (221-223). The optical arrangement (200) also comprises a main optical path (250) and a secondary optical path (251-253) for each of the prisms (221-223). The secondary optical path (251-253) runs through the corresponding prism (221-223), is connected to the main optical path (250) by means of partial reflection (272) of light and is subject to total reflection (271) at a further surface of the corresponding prism (201 20-223).
(FR) L'invention concerne un système optique (200) comprenant une structure en empilement (201) qui comporte au moins trois prismes (221-223). Ce système optique (200) comprend également un trajet optique principal (250) et, pour chacun des prismes (221-223), un trajet optique secondaire (251-253). Le trajet optique secondaire (251-253) passe par le prisme correspondant (221-223) et est relié (250) au trajet optique principal par réflexion partielle (272) de lumière, et il subit une réflexion totale (271) au niveau d'une autre surface du prisme (201 20-223) correspondant.
(DE) Eine optische Anordnung (200) umfasst eine Stapelstruktur (201), die mindestens drei Prismen (221-223) umfasst. Die optische Anordnung (200) umfasst auch einen optischen Hauptpfad (250) und, jeweils für jedes der Prismen (221-223), einen optischen Nebenpfad (251-253). Der optische Nebenpfad (251-253) verläuft durch das entsprechende Prisma (221-223) und ist durch Teilreflektion (272) von Licht mit dem optischen Hauptpfad verbunden (250) und erfährt an einer weiteren Fläche des entsprechenden Prismas (201 20-223) Totalreflektion (271).
