An optical system () for use in an underwater environment is proposed, wherein the optical system () comprises a housing which delimits an interior () of the optical system () with respect to the surroundings () in water-tight fashion, and a lens () with an outer surface (), wherein the housing comprises a mount (), wherein the lens () is received in the mount () in such a way that the outer surface () of the lens () is in fluid contact with water of the underwater environment when the optical system () is situated in the underwater environment, wherein the outer surface () of the lens () has an arched form, in particular a convex form, preferably a spherical convex form, wherein the lens () has a first arched contact face (), in particular a spherical contact face, and the mount () has a second contact face (), wherein the lens () is arranged in the mount () in such a way that the first contact face () presses against the second contact face () when the pressure of the surroundings () of the optical system () is greater than the pressure in the interior () of the optical system ().

Optical system for use in an underwater environment

Provided is a waveguide arrangement, comprising a diffractive input coupling element (), in particular a volume hologram, a diffractive output coupling element (), in particular a volume hologram, and optionally a beam expansion element (), in particular a volume hologram. The expansion element () and the output coupling element () expand a light beam in different directions.

Waveguide and devices for data reflection

An optical arrangement includes a stack structure comprising at least three prisms. The optical arrangement includes a main optical path and for each of the prisms, a secondary optical path. The optical arrangement also includes at least one interface. Each of the at least one interface is arranged between a corresponding first stack section of the stack structure and a corresponding second stack section of the stack structure. Each of the at least one interface is configured to enable relative movement of the corresponding first stack section and of the corresponding second stack section with respect to one another.

Multi-way prism

An ophthalmic instrument for the application of laser radiation in a patient's eye, particularly for the examination and/or surgical laser treatment of the cornea and the lens of the eye, includes a femtosecond laser, an objective and optical assemblies. The optical assemblies are arranged in front of the objective, and selectively vary the focus position in the coordinate direction X, Y and Z either within the region of the cornea or within the region of the lens of the eye. The objective or at least one lens group is movable relative to the eye. The variation of the position of the lens group objective shifts the focus position from the cornea to the lens of the eye and vice versa.
