1. An optical module for a lab-on-a-chip analysis device, the optical module comprising:
a light source;
a receptacle region configured to receive a lab-on-a-chip cartridge;
an image sensor;
a first filter device arranged in an excitation light path between the light source and the receptacle region, the first filter device comprising:
a first carrier element;
a first filter carrier movably arranged on the first carrier element, the first filter carrier having a first filter region and a second filter region; and
a first drive unit configured to move the first filter carrier between a first position, in which the first filter region is arranged in the excitation light path, and a second position, in which the second filter region is arranged in the excitation light path; and
a second filter device arranged in a detection light path between the receptacle region and the image sensor, the second filter device comprising:
a second carrier element;
a second filter carrier movably arranged on the second carrier element, the second filter carrier having a third filter region and a fourth filter region; and
a second drive unit configured to move the second filter carrier between a third position, in which the third filter region is arranged in the detection light path, and a fourth position, in which the fourth filter region is arranged in the detection light path.
