  "textContent": "A surveying instrument (100) is provided. The surveying instrument comprises a distance measurement unit (102) and a first optical receiver (108). The distance measurement unit comprises a transmitter (104) and a detector (106). The transmitter is configured to emit light (L1) via a first optical path (OP1). The detector is configured to receive light (L2) via the first optical path. The first optical receiver is adapted to receive light (L3) via a second optical path (OP2). The first optical path includes a front lens (110), a beam splitting unit (112), and at least one first focus adjusting element (113). The at least one first focus adjusting element is configured to adjust a focus of the distance measurement unit. The second optical path includes the front lens, the beam splitting unit and at least one second focus adjusting element (117). The at least one second focus adjusting element is configured to adjust a focus of the first optical receiver. The beam splitting unit is configured to split the first optical path from the second optical path. The transmitter and the detector share the first focus adjusting element as a common focus adjusting element.",
