Abstract : A reflectometer wherein a light having a predetermined wavelength is projected into an integrating sphere containing a sample whose reflectance is to he measured. As the projected light strikes the sample, rays are reflected back to the walls of the integrating sphere; some of which strike the area within the field-of-view of a concentrator. The rays striking within the field-of-view of the concentrator are focused upon a detector element which allows one to determine the reflectance of the sample. A control means is utilized to control the wavelength of the projected light through a spectrophotometer, and calculate the reflectance of the sample.
