US 2023/0408690 A1 · DOUBLE-END LASER RANGEFINDER

Abstract

A double-end laser rangefinder includes a ranging board, a control board, a key board which are integrated to form a mainboard. Two lens mounting bases are coaxially mounted at two ends of a main frame. First end and second end with lens-mounting bases are coaxially mounted in the main frame. Two lens groups are mounted on the two lens-mounting bases respectively. Each lens group includes a transmitting lens and a receiving lens. The receiving lenses on the first end and the second end are coaxial, the transmitting lenses on the first end and the second end are also coaxial. Coaxial arrangement of light paths of the two transmitting lenses and the two receiving lenses is realized through the main frame.
