Abstract

An optical distance meter configured to carry out a distance measurement in a first measuring mode, in which the distance meter is set for distance measurement on a retroreflective target, and a second measuring mode, in which the distance meter is set for distance measurement on a diffusely scattering target. In this case, a first aperture of the receiving channel is set in the first measuring mode, which is smaller than an aperture set in the second measuring mode.
