ABSTRACT:
An optical system having an optical axis OA and comprising: a light source; a reflector; a lens component situated therebetween; and a receiver. The light source and the receiver are separated, situated substantially symmetrically and decentered with respect to the OA. The lens component collimates the light beam from the light source. The reflector intercepts the collimated beam and to reflects it to the receiver through the lens, the collimated beam being at an angle to the optical axis. The lens component is structured to provide on the receiver an image of the light source characterized by (i) 0.05<astigmatism<0.1 waves RMS, when the lens component is not misaligned with respect to the average emission angle of the light source; and (ii) astigmatism<0.05 RMS when the lens component is tilted by of 2 to 5 degrees with respect to the average emission angle of the light source.
