Transparency Measurement Reply

Did you ever walk into a glass door? The challenge is to make the product “invisible”, i.e. homogenous without any irregularities. Transparency is more than just the ability to transmit light. The perceived quality of a transparent product is dependent on how “good” we can see the objects behind it. It can appear crystal clear, hazy or unsharp. The human eye can perceive fine variations in sharpness as well as loss of contrast.

The Objective Eye for a Clear View Reply

Our modern high-tech world is no longer imaginable without transparent products. We are so used to their “invisibility” that we only notice them if defects diminish their transparency, and consequently, their final usage. If due to varying quality of the packaging film the same chocolates appear different on the shelf, the nice holiday photos appear hazy on the smart phone, or the motorcycle helmet’s face shield easily gets scratched – then, all of this will affect our quality expectation and can even become a hazardous risk.

Haze Measurement of Ballistic Resistance Glass and Protective Shields 1

Specialty glass manufacturers are developing ballistic resistance windshields for civilian and military vehicles. The windshields consist of various layers of polycarbonate materials that contain adhesives as well as protective layers of film. Various thicknesses are application dependent. Military vehicle protective shields require superior protection due to the increase in ballistic firepower in war zones.

Thickness variations have a direct correlation to the pass-through quality of available light, night or day. BYK-Gardner’s haze-gard i technology is used to measure total light transmittance as well as haze and clarity of various products. The goal is to produce a durable product by maintaining ballistic properties and improving visual attributes.
