  • Optical arrangement for quantitative analysis instrument utilizing pulsed radiation emitting diodes
    Patent number: 4379233
    Abstract: An instrument for quantitative analysis using a matrix of radiation emitting diodes has means for assuring that a sample receives substantially uniform radiation from each diode. In the preferred embodiment a lens is used to direct the radiation beams to a focal plane where there is a matte surface diffuser backed with an aperture to provide relatively uniform radiant energy field through the aperture to a sample chamber. With this arrangement the same energy distribution contacts the test samples from each of the radiation sources.

  • Apparatus for near infrared quantitative analysis
    Patent number: 4286327
    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.
