Paper Abstract

The optical designs of the grazing incidence and the internal reflecting objective lenses for FT- IR microspectroscopy are described. Each of these lenses extends the FT-IR microscope's abilities for spectral analysis of microscopic samples. The function of both objectives is dependent upon the basic FT-IR microscope principals of remote aperture beam splitting and remote image plane masking. Dual remote confocal aperture masks are implicit for minimizing diffraction effects. These two objectives use Fourier plan masks to define the angular aperture of the incident radiation through the objective and onto the sample. These lenses are used for both imaging and spectral analysis
