Abstract
An optical device (1) includes two prism bodies (41, 42) and four side panels (71-74) attached to both prism bodies (41, 42). A cavity (9) is thereby enclosed. A first reflector (81) can be present at a first side face (81) of the first prism body (41), and a second reflector (82) can be present at a second side face (82) of the second prism body (42). At least one of the prism bodies (41, 42) and/or at least one of the side panels (71-74) can be at least in part made of a non-transparent dielectric material such as a printed circuit board. In some implementations, an optoelectronic component (90) can be attached to the respective constituent of the optical device (1).
