Description
Miniature multi wavelength light emitting diode matrix may be packed
in a hermetic case TO-5 type or in a case in which the output of
electric contacts carries out on printed circuit board (PCB). The
optical emission output carries out through the glass transparent
cap. The matrixes manufactured nowadays may consist of 8 or 10 light
emitting crystals with various wavelength in visible nearby infrared
range: 610-1300 nm with individual address. LED chips are mounted on
the thermoelectric cooler (TEC) which is build in the case and provides
wavelength temperature stabilization. Thermistor is also mounted inside
the case for checking up the matrix's temperature. The external driver
keeps the matrix's setting temperature and appropriates with TEC and
thermistor on parameters and characteristics.
Application
Spectral analysis of biological objects;
Non-invasive analysis in medical researches.
