Abstract

The results of optical studies on ceramic fibers indicate that this material may be a good reflectance standard and coating material for integrating spheres. It is highly reflective in the ir from 1.8 μ to 6.0 μ, and reasonably so at wavelengths as short as 0.25 μ. Other attractive features about this material are its stability and its availability in virtually any size. Spectral reflectance and goniometric reflectance curves are presented, and a calculation is given that shows the improvement in efficiency when the material is used in an integrating sphere the size of that in the Beckman DK-2 spectroreflectometer.
