Window assembly for thermal gradient spectrometer

摘要

An analyte detection system for non-invasively determining the concentration of an analyte in a sample is described. The detection system includes a window assembly consisting of a main layer adapted to allow electromagnetic radiation to pass therethrough, and a heater layer adapted to exchange heat to the sample. The system also includes a detector adapted to detect electromagnetic radiation emitted by the sample and passed through the window assembly. The analyte detection system also includes a control system in electrical communication with the heater layer and adapted to cause the heater layer to exchange heat to the sample. The main layer of the window assembly may be made from a variety of materials such as germanium, silicon, and chemical vapor deposited diamond.
