Abstract
An optical system is provided with an optical assembly and a wavelength division multiplexer surface for transmitting a light beam. The optimal alignment of these light beams is accomplished by adjusting a steering device, which includes an optical wedge or a universal coupling, until the light path of the transmitted light beam through the optical assembly aligns with the light path of the transmitted light beam through the wavelength division multiplexing surface.
