FTIR: Educational 408


Interspec 408 is an educational Fourier transform infrared (FTIR) modular
spectrometer for teaching spectroscopy in the science and university labs to
promote the use of infrared spectroscopy as a general-purpose, broad-based
measurement tool, and to enable the use of state-of-the-art FTIR technology
for teaching and science purposes. With the wavenumber range from 7000 to
400 cm-1 and spectral resolution of 2 cm-1, the interferometer module with
detector system, power supply and data acquisition system forms an open
architecture sample compartment modular spectrometer capable to use most
of FTIR accessories available in the market. It makes the instrument very
flexible for different kind of applications in science and teaching lab. The
interferometer module has a transparent plastic cover to allow visual access
to all of it’s major parts, 25-mm collimated output beam, a multicoated KBr
beamsplitter, a high-intensity ceramic IR source, and an USB interface.
FTIR spectroscopic software Interspec for Windows is a program for running
the spectrometer and for complete handling of measured infrared data.
