The vacuum
compatible Laboratory Portable FTIR SpectroReflectometer
(LPIR FT V) is a unique instrument for easily
and quickly measuring total hemispherical
spectral reflectance of almost any surface
regardless of size. This spectral reflectometer makes
measurements over the infrared region of
the spectrum from 2.5um to 25um. The LPIR FT
incorporates unique optical, mechanical,
and electronic designs to provide state-of-the-art
performance in a compact instrument.
The LPIR FT V user interface provides a one
button operation for an automatic measurement
scan. For additional flexibility, selectable
options for specific measurments are provided,
including multiple scan averaging. The menu-driven
display leads the user through the setup
and operation of the LPIR FT V, including
the display of the measurement data. Automatic
integration of the spectral reflectance
data is performed to calculate and display
total mopmal emittance. An internal hard
disk allows storage of thousands of measurements.
Along with its powerful and user friendly
PC/Power Box, the LPIR-FT combines AZ Technology's
patented optical design with an interferometer
and control electronics. An AZ Technology
application software is provided for retrieving,
archiving, and displaying LPIR FT V data.
The software provides all the tools necessary,
from data analysis to publication quality
graphics.
