Abstract

A method and a device for inspecting an optoelectronic component are disclosed. In an embodiment, the method includes exciting at least one electromagnetic resonant circuit, formed by the at least one optoelectronic component and the connection board, such that the at least one optoelectronic component emits electromagnetic radiation, wherein exciting the electromagnetic resonant circuit comprises applying an electrical alternating voltage in the electromagnetic resonant circuit by generating a temporally variable electromagnetic alternating field by a first coil and a second coil, wherein the first coil and the second coil are movable with respect to the connection board.
