Abstract:
An optical system for imaging an input beam from an input to an output beam at an output, comprising:a lens adapted for receiving the input beam from the input, and a reflecting device adapted for reflecting the input beam from the lens back to the lens, whereby: the lens is adapted for converging the beam reflected by the reflecting device to the output, the input and the output are both located substantially in a focal plane of the lens and off axis, with respect to an optical axis of the lens, on opposing sides from the optical axis of the lens, the reflecting device is located on a side opposite, with respect to a principal plane of the lens, to the side of the input and the output, and wherein an angle of radiation from the input provided with respect to the optical axis of the lens is adjusted for adjusting the distance between the reflecting device and the lens.
