Abstract
Systems and method are disclosed for measuring an analyte (e.g., glucose) in a fluid (e.g., blood) using a tunable source. The system can draw blood from a patient and deliver the blood to a sample cell. Some or a particular component of the fluid (e.g., plasma) may be positioned at a sample portion of the sample cell for measurement. The sample cell can include a cuvette with two window pieces defining a gap for fluid analysis. Wider gaps can facilitate measurement of larger biological fluid components, and laser optical sources can provide sufficient power to traverse larger gaps. Tunable sources can provide for measurement of a wider variety of components. Aspects of the system can be adjusted to accommodate measurement of multiple analytes with multiple wavelengths.
