摘要： A reflectometer wherein a light having a predetermined wavelength is projected into an integrating sphere containing a sample whose reflectance is to be measured. As the projected light strikes the sample, rays are reflected back 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.

摘要： Disclosed is an integrating sphere for measuring the diffuse reflectivity of material samples in the infrared. The sphere is disposed in an airtight vacuum chamber under an atmosphere that does not absorb in the infrared. The sphere has two positions at which a sample may be mounted, one on a rod at the sphere's center, another on the sphere's wall, each mounting position corresponding to two different modes of testing samples. The rod acts as a mounting pedestal for a center mounted sample, and is rotatably mounted about its elongate vertical axis so that the sample can rotate with the rod in a horizontal plane. The rod penetrates the sphere and the chamber, and terminates in a knob or handle by which the rod can be rotated to position the sample at a preselected angle. Adjacent to the position for wall mounting, there is a sample heater. This configuration allows one to measure diffuse reflectance of a sample as a function of incidence angle and temperature. In the center-mount configuration, the handle enables one to anglularly reposition a center mounted sample without the need to vent and replenish the chamber's atmosphere after each test.
