Sphere tests were performed in a 76 Labsphere integrating sphere located in a lab ambient of 25º C. Self absorption correction is applied to the sample being tested to correct for mismatches between the sample and the standard lamp used to calibrate the sphere. Goniometric measurements are made using a goinophotometer using a photodetector with f1 photopic correction factor of <1.5%. Ambient conditions are controlled to 25º C ± 1º C.
