Under a filter an LED pulses light at a ruthenium coated dichroic mirror. A dichroic mirror acts as an interference filter used to selectively pass light of a specific wavelength through it. This light is then collected by a photodiode that generates a small electrical current which is passed to the PCB where a high accuracy timing circuit measures the rate of decay of the excited fluoroform. ...
