Laser tracker for industrial measuring, for continuously determining the position and continuous tracking of a target embodied as a retroreflector or at least having a retroreflector, the laser tracker comprising at least the following: • a base defining a vertical axis, • a beam guiding unit for emitting measurement radiation (17, 21) from a measurement radiation emergence aperture and for receiving at least some of the measurement radiation (17, 21) reflected at the target, wherein ∘ the beam guiding unit is swivelable in a motor-driven manner about the vertical axis and an inclination axis relative to the base, and ∘ a measurement axis is defined by an emission direction of the measurement radiation (17, 21), • a distance measurement unit for precisely measuring the distance to the target by means of the measurement radiation (17, 21), • an angle measurement functionality for determining an alignment of the beam guiding unit relative to the base and • a target acquisition unit for determining an impact point of radiation reflected by the retroreflector on a sensor of the target acquisition unit and for producing an output signal for controlling a fine targeting functionality and a target tracking functionality, wherein distance and position of the target relative to the laser tracker are continuously determined, characterized by a heat influence reduction component (43, 43') which is embodied as a pipe-shaped body with a length of at least 2 cm and with a substantially airtight pipe wall which is embodied and arranged on the laser tracker in such a way that said pipe-shaped body surrounds at least part of a near region free beam path downstream of the measurement radiation emergence aperture, i.e. a free beam path of the measurement radiation downstream of the measurement radiation emergence aperture in the near zone of the laser tracker, such that, as a result thereof, warm air which is produced by heating of internal components of the laser tracker is prevented from passing through the near region free beam path covered by the body, namely guided therearound, during the heat-induced rise thereof and therefore there is a reduction in turbulence in the near region free beam path which is caused by such rising warm air. • a base defining a vertical axis, • a beam guiding unit for emitting measurement radiation (17, 21) from a measurement radiation emergence aperture and for receiving at least some of the measurement radiation (17, 21) reflected at the target, wherein ∘ the beam guiding unit is swivelable in a motor-driven manner about the vertical axis and an inclination axis relative to the base, and ∘ a measurement axis is defined by an emission direction of the measurement radiation (17, 21), ∘ the beam guiding unit is swivelable in a motor-driven manner about the vertical axis and an inclination axis relative to the base, and ∘ a measurement axis is defined by an emission direction of the measurement radiation (17, 21), • a distance measurement unit for precisely measuring the distance to the target by means of the measurement radiation (17, 21), • an angle measurement functionality for determining an alignment of the beam guiding unit relative to the base and • a target acquisition unit for determining an impact point of radiation reflected by the retroreflector on a sensor of the target acquisition unit and for producing an output signal for controlling a fine targeting functionality and a target tracking functionality, wherein distance and position of the target relative to the laser tracker are continuously determined,
