摘要:
An optical analyzer measuring the reflectivity of a moving article in an in-line sputtering deposition system. The optical analyzer includes a light source which provides a light beam. Light is reflected from an optical coating of a moving article into a concentrator, which captures and directs the reflected light to a detector. The analyzer may be mounted in an evacuable chamber in which the end walls have openings to allow passage of the article.
摘要:
In one embodiment, a magnetron assembly comprises a plurality of magnets and a yoke configured to hold the plurality of magnets in at least four independent linear arrays. The plurality of magnets is arranged in the yoke so as to form a pattern comprising an outer portion and an inner portion. The outer portion substantially surrounds the perimeter of the inner portion. The magnets used to form the outer portion have a first polarity and the magnets used to form the inner portion having a second polarity. The outer portion of the pattern comprises a pair of elongated sections that are substantially parallel to one another. The outer portion of the pattern comprises a pair of turnaround sections, wherein each turnaround section substantially spans respective ends of the pair of elongated sections and wherein each turnaround section comprises a plurality of magnets having the first polarity. Other embodiments are described.
摘要:
An article comprising a transparent or translucent polymer substrate and a transparent or translucent coating applied thereto in which the refractive index of the coating material substantially matches the refractive index of the polymer substrate. The invention also relates to a method for making an article comprising a polymer substrate and a coating in which the refractive index of the coating substantially matches the refractive index of the polymer substrate.
摘要:
A method and system for designing and manufacturing a high-performance, optimized optical interference coatings that have a minimal number of layers. Index of refraction, absorption coefficient, and thickness values are selected for each of the layers in the design so as to cause the reflectance of a coated object to be zero for a given wavelength. Materials that with the selected properties are manufactured by mixing two or more preexisting available materials.
摘要:
A system for evaluating the reflectance of an object (e.g., a CRT) that is coated with an anti-reflective coating material is disclosed. The quality and/or uniformity of the coating is evaluated by a reflectometer. The reflectometer is positioned relative to the object by non-contact sensors. Reflectance data gathered by the reflectometer is analyzed to determine to what extent the actual coating differs from the optimal (i.e., ideal) coating. A feedback system modifies the coating process for subsequent objects in an attempt to fine-tune the coating process and achieve optimal anti-reflective coatings for later objects passing through the system.
摘要:
A multilayer antireflection coating for a temperature sensitive substrate such as plastic. One layer is a DC reactively sputtered metal oxide which may be deposited quickly and without imparting a large amount of heat to the substrate. Another layer has a refractive index lower than the substrate.

摘要:
High purity (95-99.5 percent) red, orange and yellow filters are disclosed which comprise a periodic stack of relatively low index of refraction dielectric material (L) such as SiO.sub.2 or MgF.sub.2 and absorbing relatively high index material such as silicon or Fe.sub.2 O.sub.3. Together, the low and high index materials provide a high index ratio (typically 1.7 to 2.5). The filters are fabricated according to designs such as (H/2 L H/2).sup.n, typically using only 5 to 7 layers. Despite the very small layer count, these filters provide overall optical performance which is at least the equivalent of all-dielectric filters of 30 or more layers, with color purity that is unachievable by all-dielectric filters and simple low cost design. In addition, our filters have inherently low stress levels and absorb and reflect unwanted light such as blue light. As a consequence, the filters are ideally suited for coating on flexible substrates such as plastics and for coating on lamp envelopes to form red or yellow bulbs which are ideally suited, for example, for use as automobile tail light bulbs, side marker bulbs and turn signal bulbs.
