An optical transceiver including a transmitter and a receiver fixed relative to one another. The transmitter includes a light source and a directing element, wherein the directing element is configured to direct light emitted from the light source away from the optical transceiver along a light path, and wherein the directing element is configurable to adjust the light path, and the receiver includes a lens having a focal region at a focal length and a detector arranged at the focal region of the lens, The receiver is configured with a function of merit FOM=PSAAperture (A/D): wherein PSAAperture is the projected solid angle of the receiver, A is the area of the aperture of the receiver, D is the active area of the detector, and the FOM is equal to at least 1.5.

A free-space optical receiver comprising a catadioptric lens having a focal region at a focal length, and a detector arranged at the focal region, wherein the lens comprises a concave front surface and a flat rear surface, a flat reflector on the front surface and a flat reflector on the rear surface, wherein the flat reflector on the rear surface is arranged to reflect light that passes through the concave front surface to the flat reflector on the front surface, and the flat reflector on the front surface is arranged to reflect the light to the focal region of the lens.
A free-space optical receiver comprising a catadioptric lens having a focal region at a focal length and a detector arranged at the focal region, wherein the detector is embedded within the lens, between a light-receiving front surface and a reflecting rear surface of the lens, and wherein the lens is configured such that light entering the lens through the light-receiving front surface is reflected towards the focal region by the reflecting rear surface.
