Abstract
A prismatic joint for an optical swiveling device has a first prism rotatably mounted about a first rotation axis and a second prism, rotatably mounted about a second rotation axis with respect to the first prism. The first rotation axis and the second rotation axis intersect one another at an intersection angle of 45°. The first prism and the second prism have a respective first side surface and a second side surface, as well as a base surface. The first side surface is inclined through the intersection angle with respect to the base surface, and the second side surface is inclined through half the intersection angle with respect to the base surface. The first and second prisms project substantially mirror-image symmetrically along the first rotation axis, and a third prism is disposed with its side surfaces adjoining, the first and the second prisms.
