    Abstract: In one embodiment, an apparatus may include a light source. The apparatus also includes a measuring laser, such as a semiconductor laser. The measuring laser is configured to generate pulses with a maximum pulse duration of 10 ns. A wavelength of maximum intensity of the measuring laser radiation generated by the measuring laser ranges from 400 nm to 485 nm inclusive. The measuring laser radiation is used for distance measurement by means of LIDAR, for example in a car headlight.
