Transmission Haze and Clarity

Atlas uses a BYK Gardner Haze-Gard Model 4725 to measure haze, total transmittance, and clarity. This instrument conforms to ASTM D1003 and is used in conjunction with SAE J576 exposure programs. The specimen surface is illuminated perpendicularly with the transmitted light, measured with an integrating sphere (0°/diffuse geometry). The spectral sensitivity conforms to CIE standard spectral value function "Y" under illuminant C with a 2° observer.
