Optical detection apparatus for multi-channel multi-color measurement and multi-channel sample analyzer employing the same

A multi-channel sample analyzer comprising:

• a light source unit for irradiating light onto each of a plurality of samples;
• an optical detection unit for detecting light beams emitted from the plurality of samples;
• and an optical transport unit for receiving the light beams emitted from the plurality of samples and transporting them to the optical detection unit,
• wherein the optical detection unit comprises
• an optical detector;
• a filter wheel having at least two color filters connected to each other in the shape of a disk;
• a plurality of optical channels through which a plurality of beams of light transported from the optical transport unit enter the filter wheel;
• and
• a mirror unit including a plurality of mirrors for sequentially reflecting each of the plurality of beams of light transmitted through the filter wheel to the optical detector,
• wherein the mirror unit rotates together with the filter wheel.
