Abstract

Some embodiments of the invention relate to a coordinate measuring machine for determining the position and/or for continuous tracking of a target embodied as a retroreflector or at least having a retroreflector. In some embodiments, the coordinate measuring machine may be a laser tracker. The coordinate measuring machine may include comprising at least a base defining a vertical axis, a support swivelable relative thereto and, tiltable thereto a beam guiding unit for emitting measurement radiation for receiving at least some of the measurement radiation reflected at the target. In some embodiments, the coordinate measuring machine includes a heat influence reduction component that may be configured to prevent and/or actively reduce heat emission, and/or obstruct or prevent warm air from passing through the near region free beam path.
