Abstract

Integrating sphere measurements are presented in the wavelength range from 0.35 micrometers to 18 micrometers . The spheres are used with a rapid scan FTIR Bruker IFS66. The design of the sphere allows the spectral reflectance and transmittance to be determined, both as normal hemispherical and as normal diffuse values. The excellent resolution and reproducibility is demonstrated by noise spectra and some measurements. The easy sample handling makes this instrument a versatile tool for the development of new materials as well as for aging investigations.
