Reflectometers for Absolute and Relative Reflectance Measurements in the Mid-IR Region at Vacuum
We demonstrated spectral reflectometers for two types of reflectances, absolute and relative, of diffusely reflecting surfaces in directional-hemispherical geometry. Both are built based on the integrating sphere method with a Fourier-transform infrared spectrometer operating in a vacuum. The third...
