The invention relates to an optoelectronic device, in particular an optoelectronic sensor device, comprising a support device (12), which has at least one optoelectronic transmitter (40) and at leastone optoelectronic receiver (42) on an upper face, and at least one first optical element (14), a second optical element (16), and a third optical element (20), which are arranged above the support device (12) in a layer arrangement. The second optical element (16) is arranged above the first optical element (14), and the third optical element (20) is arranged above the second optical element (16). Each of the at least three optical elements comprises a lens element, an aperture element, or a filter element. The optoelectronic element also comprises a retaining device (18, 20) which retains atleast the first optical element (14) and the second optical element (16) relative to the support device (12) and partly surrounds said elements. Furthermore, the retaining device (18, 20) either retains the third optical element (20) relative to the support device and partly surrounds said element or forms the third optical element. The device has a modular design in the manner of a modular system, wherein the device is assembled from different separate components. The modular design allows the optical properties to be set in a simple manner.
