Transparency is determined by material selection, process conditions and enduse. Process fluctuations can greatly influence optical properties.

Clear communication in R&D and Quality Control requires objective measurement methods instead of subjective visual assesments.

haze-gard plus quantifies the visual perception with objective measurement values:

• Total transmittance
• Transmission haze
• Clarity

Therefore, product quality can be controlled and improved as part of routine quality checks.

The industry standard according to ASTM.

• Easy and fast operation Open sample area for small and large specimens. Automatic calibration and menu guided operation - just push a button. • Precise and reliable Reference beam, long term calibration, self-diagnosis and enclosed optics guarantee accurate readings - anytime. • Documented quality Built-in statistics, stored data, RS-232 and printer interface allow for flexible documentation - key for ISO 9000.

Hazy material reduces contrast and appears milky.	Poor clarity distorts contours and deteroirates with increasing distance.
