FIELD: instrumentation.SUBSTANCE: invention relates to the field of optical instrument making, namely, to a receiving lens system for an optical range finder, and also to an optical range finder with such receiving lens system. The application describes a receiving lens system (7) for an optical range finder (1), designed for receiving of optical radiation reflected from the object and having a polymer lens (12) and a glass lens (11) arranged on the trajectory (6) of received beams, the distance between which is controlled, due to making the polymer lens adjustable in the position relative to the fixed glass lens. And also an optical range finder with a receiving lens system.EFFECT: adjustment of focus distance of a receiving lens system, reduced sensitivity to impact of temperature and/or moisture and/or contamination.9 cl, 1 dwg |
