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.
