The methods and devices use one or more diffractive reflective surfaces to enable a light beam incident on a measurement chamber to be steered so as to be reflected inside the measurement chamber to achieve relatively long optical paths in the measurement chamber. The liquid sample may be blood or blood serum. The measurement chamber may be provided in a microfluidic device, for example a centrifugal microfluidic device. Some embodiments enable multiplexing of different wavelengths or path lengths. Some embodiments make use of multiple returned beams to determine the position and/or orientation of the measurement chamber."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Photometric device and method","description":"Disclosed are methods and devices for photometric measurements of a liquid sample.
