ASTM D1003 Haze requires a Procedure B Haze Meter design where the light source mounted on the sphere and the detection opposite the sample sphere opening. Procedure B instruments like the Vista are transmission capable spectrophotometers that meet a few extra design criteria, such as number and size of openings in the sphere and size of detection beam relative to size of entrance and exit ports of the sphere. The VISTA fully complies with all of these dimensions.
Each VISTA is shipped with a certificate showing compliance to ASTM D1003 Haze performance by reading 5 Haze Standards (1%, 5%, 10%, 20%, 30% Haze). To obtain a copy of this certificate, contact HunterLab with your VISTA serial number.
