The LPSR-300 measures total hemispherical reflectance throughout the solar range using a monochromatic light source to pass a narrow-wavelength band of light into the integrating sphere to illuminate the sample. The sphere collects light reflected from the sample in all directions, and averages it by multiple chaotic reflections from the 115mm (4.5 in) integrating sphere’s walls, which have the effect of evenly illuminating the entire surface of the integrating sphere. Detectors detect the average reflection by observing the sphere walls. In practice, sphere coatings are not perfect, diffuse reflectors. Detectors are spatially and directionally nonuniform, and integrating spheres have hole losses. These factors determine the accuracy of the reflectance measurement. This is particularly important when measuring samples ranging from specular to diffuse. The most critical feature for non-ideal integrating sphere design is to maximize neither the detector field-of-view of the sphere wall while not permitting the detector to view the sample, the first specular reflection onto the sphere wall, nor the direct illumination of sphere wall by the incident beam. The design of the LPSR eliminates the major errors in the measurement of either specular or non-specular samples. This is accomplished by employing unique detector optics with integral baffles. |
