Zetian - Model ATP-200C -FTNIR Spectrometer
The spectrometer in FTNIR is a compact, lightweight and stable near infrared spectrometer based on Fourier transform technology. The spectrometer adopts a double hollow corner reflector with double pendulum design, which has the advantages of permanent alignment, good anti-vibration and anti-thermal effect; a InGaAs detector with 2-stage cooling which has the advantages of high sensitivity, low detection limit, high speed and high resolution and is very suitable for various complicated working conditions. This product can be used with different infrared accessories in different applications, which is specially designed to provide optimal solutions for system integrators of customized FTIR analyzers.
The light from the light source is divided into two beams by the beam splitter. One beam is
transmitted to the first moving mirror, the other reflected to the second moving mirror. The two
beams are then reflected back to the beam splitter by the first and second moving mirrors, which
wobbles at a constant speed to form optical path difference between the two beams, resulting in
interference. The two beams merged at the beam splitter then pass into the sample cell, get the
interference light with sample information and reaches the detector. The obtained signals are finally
processed by Fourier transform to generate a spectrogram with infrared light absorbance or
transmittance on the vertical axis and wavenumber or wavelength on the horizontal axis.
