Lumiflex 50/50: Lumiflex 50/50 is a problem solving fabric formulated to provide double sided viewing, with nominally balanced gain from viewing areas on either side of the fabric. to a front projection screen’s set up, Lumiflex 50/50 provides viewing utility through the fabric as well and offers normal reflective capability of a front screen. Lumiflex 50/50 must be used in light-controlled areas, as it is susceptible to ambient light washout from both sides. Lumiflex 50/50 delivers fairly wide viewing angles, but is less uniform than the superb standard set by other Stewart Filmscreen products.
Silver 3D is a specialty fabric designed to optimize stereoscopic, two channel 3D displays. The fabric employs special metallic elements, formulated to preserve light polarization. The high gain and high contrast of the fabric helps compensate for the losses incurred when using polarization filtration technology. Silver 3D offers a wider viewing cone then competing fabrics with similar gain specifications. The open/closed ratio, otherwise known as “ratio of extinction”, of Silver 3D is the industry benchmark for front projection fabrics.
In order to produce a high ratio of extinction, special pigmentation and binder chemistry is required. These special ingredients allow the high performance of the fabric, but have impact in the steps required to successfully handle, install, and maintain the fabric. Silver 3D is high in gain and contrast which means that any hand oil, or soil smudges will be very apparent.
Silver 3D is less plasticized than typical Stewart Filmscreen fabrics, a normal plasticization level is found to interfere with the measured ratio of extinction. The binders necessary for the preservation of the optical coating are very high in molecular weight and somewhat stiff as a result. Contact Stewart Filmscreen for more details on this custom material, its applications, and recommended handling.
STEWART BLACK R.P.
Stewart Black R.P. is a specialty fabric formulated exclusively for 3D special effects. Stewart Black R.P. has a very high ratio of extinction, but a very narrow viewing cone, and is less uniform than most Stewart Filmscreen Corp fabrics. Stewart Black R.P. is most often used in short duration 3.D. theme park displays and laboratory 3.D. applications.
