ABSTRACT:
An apparatus for near infrared quantitative analysis with an infrared emitting diode (IRED) source utilizes narrow bandpass filters and silicon detectors to provide highly accurate and inexpensive measurement. A narrow bandpass filter in the light path of the IRED passes wavelengths outside the half power bandwidth points of the IRED. A silicon detector together with a sensitive amplifier is used to accurately measure linearly up to six decades of light sensitivity at desired wavelengths.
