Abstract:

A reflectometer and a method for measuring the reflectance and transmittance of material using an integrating sphere and a light concentrator. The reflectance and transmittance measurements are performed as a function of the angle of incidence of a beam of light onto a sample and reference material. In a preferred embodiment, a CHC-lens concentrator having a high f and a low index of refraction is used.
