Across the worldwide markets. ⊙ Full spectrum measurement and DOAS (Differential Optical Absorption Spectroscopy) algorithm, excelling in accuracy, repeatability and anti-interference with moisture, dust. ⊙ Pulse Xenon Lamp used as light source. This compact module has a built-in light source, control circuit, and MEMS-FPI spectrum sensor consisting of an InGaAs PIN photodiode and MEMS-FPI (Fabry-Perot Interferometer) tunable filter which can vary its transmission wavelength by changing the applied voltage. Its design combines high performance with rugged construction and operational convenience with reliable operation. The programmable digital spark source, optimized optical system, auto spectrum. ical spectrum. Two different mirror radii are available, 75 mm and 18. 75 mm, which give a free spectral range (FSR) of 1GHz and 4GHZ nterferometer. At precisely the confocal spacing, each mirror images the other back upon itself so that a paraxial ray is re-entrant, i.
