Filter device for an optical module for a lab-on-a-chip analysis device, optical module for a lab-on-a-chip analysis device and method for operating an optical module for a lab-on-a-chip analysis device

A filter device for an optical module for a lab-on-a-chip analysis device, in which the optical module includes a light path, the filter device comprising:

• a carrier element configured to be arranged in the optical module;
• a filter carrier movably arranged on the carrier element, the filter carrier having a first filter region and a second filter region;
• and
• a drive unit configured to move the filter carrier between a first position, in which the first filter region is arranged in the light path, and a second position, in which the second filter region is arranged in the light path,
• wherein:
• at least one of the first filter region and the second filter region is formed as an empty position configured such that light passes through the at least one of the first filter region and the second filter region unfiltered;
• the optical module includes a further light path;
• the filter carrier includes a first filter wheel;
• the filter device further comprises a second filter wheel rotatably arranged on the carrier element, the second filter wheel including a further first filter region and a further second filter region;
• and
• the drive unit is configured to move the second filter wheel between a further first position, in which the further first filter region is arranged in the further light path, and a further second position, in which the further second filter region is arranged in the further light path.
