Abstract

A sensor unit for detecting reference and measurement radiation for a distance measurement device has a sensor element and an optical shielding device. The sensor element has a first detection region for detecting measurement radiation and a second detection region for detecting reference radiation. The optical shielding device is positioned in relation to the sensor element and fastened, and the optical shielding device optically separates the first and second detection regions from each other. The optical shielding device further comprises a first recess and a second recess which are permeable to optical radiation of a first wavelength range.
