1. A detector (110) for determining a position of at least one object (112), the detector (110) comprising:
at least one dichroic filter (130), wherein the dichroic filter (130) has a wavelength dependent and angle dependent transmission spectrum;
at least one optical sensor (114), wherein the optical sensor (114) has at least one light-sensitive area (116), wherein the optical sensor (114) is designed to generate at least one sensor signal in response to an illumination of its light-sensitive area (116) by the light beam (120) having passed through the dichroic filter (130);
at least one transfer device (126), wherein the at least one transfer device is adapted to guide the light beam onto the optical sensor; and
at least one evaluation device (134) configured for determining a first sensor signal generated in response to illumination by the light beam (120) having at least one first wavelength and a second sensor signal generated in response to illumination by the light beam (120) having at least one second wavelength, wherein the evaluation device (134) is configured for determining at least one longitudinal coordinate z of the object by evaluating a combined signal Λ from the first and second sensor signals.
