OPTISK ANORDNING FOR ELEKTROOPTISK AVSTANDSMETARE

摘要

The invention relates to an optical arrangement for a range-finder having an observation path of beams and a measuring path of beams constituted of an objective and a reflection system arranged in the near-axial room behind and in close contact to the objective. The reflection system is laterally displaced in parallel to the objective axis and has a second reflecting face at right angles to the optical axis and a first reflecting face inclined by 45 DEG relative to the optical axis, the extension of the latter at right angles to the optical axis is smaller than the corresponding extension of the second reflecting face.
