Racing Optics SpeedStack 7 Laminated Tearoffs

Description

The Racing Optics Laminated Tearoff System consists of 7 tearoffs laminated together that install as one piece. When attached to the helmet's face shield, it allows for a quick and easy change on the fly. When the face shield becomes dirty, simply peel off the next layer, and you have a clean shield. It's not necessary to change during a time-consuming pit stop. They provide high visibility and low reflection while eliminating fog between layers. The SpeedStack 7, SmokeStack 7, and the AmberStack 7 each contain 4 laminated 2 mil. stacks of 7 tearoffs (total of 28 tearoffs). They are available for helmets like simpson, vudo, invader, shark, voyager, hjc, snoei, bike, bell, bieffe, rci, matrix, arai, impact, vapor, charger, rx, g-force, bandit, champ, and sparco.

THE SpeedStack7™ SOLUTION
As mentioned earlier, reflection is caused by the speed of light slowing down as it enters a transparent material. When light travels through multiple layers of different materials, and keep the light at the same speed, no new reflections are created. Racing Optics has created the SpeedStack7™ (U.S. Patent 6,388,813) by optically laminating seven layers of tearoffs together. The laminated tearoffs of the SpeedStack7™ displace any air in the Stack. Thus eliminating the reflections between layers. A seven layer SpeedStack7™ has about the same optical characteristics as a single tearoff! SpeedStack7s™ can be layered, giving the driver up to twenty-one or more tearoffs for those long races. This allows the driver to have better visual acuity than ever experienced before from the start of a race to the checkered flag.

Transmission Measurements
See How It Works Tab For Bar Graph.   In the first bar graph, the light transmission is measured comparing the SpeedStack7™, and a standard 2mil thick tearoff. With only one layer the light transmission of both 2mil tearoff and SpeedStack7™ are the same. As additional layers are added, the standard 2mil tearoffs decrease rapidly to about 50 percent while the SpeedStack7™ remains almost constant with only about a 10 percent change in transmission.

Reflection Measurements
See How It Works Tab For Bar Graph.  In the second bar graph, the reflection is characterized for the SpeedStack7™, and the standard 2mil tearoffs. Again with only one layer the SpeedStack7™ and the standard 2mill tearoff are the same in reflection. As layers are added the reflection increases to over 40 percent for the standard tearoff, but the SpeedStack7™ remains constantly low in reflection with only a 3% change.

Vision Index
See How It Works Tab For Bar Graph.  The third bar graph is the Vision Index. It demonstrates the effect of the combination of the transmission values divided by the reflection values. As the reflection on the inside of the face shield increases and reduces contrast ratio, it competes with outside

Racing Optics SpeedStack 7 Laminated Tearoffs - How It Works

	Tearoff on Helmet Tearoffs are universally used in motorsports as multi-layered disposable lenses. As the race proceeds, the top layer accumulates mud, rubber, fuel, oil, and water, which will eventually obscure the driver's vision. The top layer of the tearoff is removed by the driver, which reveals the next clean layer.
