DISPLAY READOUT WINDOWS OPTICAL FILTERS

 ADC Cast Optical Sheet

The continual advancement in resolution, reliability and performance of electronic display technologies requires display readout windows and optical filters that do not compromise readability or contrast of the information displayed. The "see-through" problem in the past has been solved by using various transparent materials such as glass, acrylic, cellulose acetate butyrate and polycarbonate. These materials all have some disadvantages, such as, impact resistance, chemical resistance, scratch resistance, clarity, weight, yellowness upon aging, workability, consistent antiglare finishes, crazing and custom colors.

Optical Polymers International supplies optical sheet cast from a family of thermosetting polymeric blends based on ADC, Allyl Diglycol Carbonate monomer. CastADCsheet has unique optical and mechanical properties superior to other transparent materials without any of their disadvantages. ADC, sometimes called CR-39®, was developed as a substitute for glass and is often called organic glass. It has almost the same refractive index, chemical resistance and similar mechanical properties as glass. ADC monomer has been used for many years in the manufacture of ophthalmic lenses. More than 80% of ophthalmic plastic lenses are made of ADC.

Optical Polymer's ADC sheet is cast from a family of proprietary allyl diglycol carbonate formulations that produce optical sheet with superior properties for all display applications. Three types of sheet are available: standard, hi-temperature resistant and hi-impact resistant. ADC is available with three "cast in" matte surface finishes for superior glare reduction.

Display readout windows and optical filters are custom fabricated from ADC to meet the most demanding applications and are available in almost any thickness, shape or color. ADC is accurately cut to size with state of the art precision laser cutting technology.

Information Display Readout Windows And Contrast Enhancement Filters

The "see-through"or window problem and display contrast enhancement, historically, has been solved by using glass, followed by transparent plastic sheets such as acrylic or PMMA (polymethylmethacrylate) and more recently PC (polycarbonate). These transparent plastic materials have replaced glass in many applications mainly because of their lighter weight, better impact resistance, workability, easily applied antiglare matte finishes, and they are easily colored.  These transparent plastic materials, however, exhibit some deficiencies when compared to glass, such as:

• Poor Chemical And Solvent Resistance

• Aging Problems, Micro-Cracking, Haze

• Poor Scratch Resistance 

These deficiencies may result in the loss of optical, mechanical and contrast enhancement properties of the window or filter. For these reasons, the previously mentioned transparent plastic materials may not always provide the best alternative to glass for information display readout windows and contrast enhancement filters.

The main properties of ADC cast optical sheet are superior to all other transparent plastic materials and provide an alternative to glass. The following table summarizes the main properties of Optical Polymer's International ADC cast sheet compared to the most popular transparent readout window and contrast enhancement filter materials:

Instead of retaining the traditional style, Monclerslife hired some great graduates from Istituto Marangoni in 1988, which produced it the most well known brand name that winter season. In the part of color, fresh color, such as red, yellow, blue and green were pieced together by the young designers, and the skinniness and coat cloth had been mixed cut, which shaped the unusual aesthetical standard from the down jacket. From then on, Monclerslife grew to become the necessaries on the European's, no matter you were a pop star or a common folks, all people would have such kind of down jacket, which made by Monclerslife. The big shots of style highly praised in succession that Monclerslife had made the popularity of outdoor sports and leisure down jacket ten years ahead. Style magazines such as ELLE had been scramble to report that Monclerslife was a brand name needless to pay for any stars as the face, since it had been chosen consciously by persons.
