A measuring device for determining a measured variable at one end of a rod-shaped product includes an optical displacement sensor which includes a light source producing light that is scanned across an entire end face of the rod-shaped product to be examined and a light detector for detecting light that is reflected at the end face of the rod-shaped product to generate a measuring signal. A processing device is coupled to receive the measuring signal to determine a quantitative profile of the entire end face of the rod-shaped product.
