LPIR FT V, Vacuum Compatible Laboratory Portable FTIR Spectroreflectometer

The vacuum compatible Laboratory Portable FTIR SpectroReflectometer (LPIR FT V) is a unique instrument for easily and quickly measuring total LPIR FT-Vhemispherical 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 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 V data. The software provides all the tools necessary, from data analysis to publication quality graphics.
