LPIR FT, Laboratory Portable FTIR Spectroreflectometer
The Laboratory
Portable FTIR Spectroreflectometer (LPIR FT)
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 is also available in a vacuum chamber compatible version; LPIR FT V.
The LPIR FT 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, including
the display of the measurement data. Automatic
integration of the spectral reflectance
data is performed to calculate and display
total normal 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 data.
The software provides all the tools necessary,
from data analysis to publication quality
graphics. (SOC 400T)
