摘要:
A bismuth-based glass composition according to the present invention contains Bi2O3, B2O3 and ZnO, wherein the bismuth-based glass composition has a Bi2O3 content of 55 to 80 mass % and further contains 0.1 to 5 mass % of at least one of SrO and BaO as an RO component. Preferably, the bismuth-based glass composition according to the present invention has a linear expansion coefficient of (65 to 95)×10−7/° C. at 30 to 300° C. and a softening point of 450 to 530° C. There is a problem that bismuth-based glasses are often structurally unstable, are crystalized during firing and lose their flowability due to such crystallization so that it is difficult for the bismuth-based glasses to secure good adhesion strength and airtightness. By contrast, the bismuth-based glass composition according to the present invention is transparent and is less likely to be crystallized during firing.

摘要:
A method is provided for coating optical lenses and other optical articles with anti-reflection (AR) coatings. The lenses have low reflectivity, provide a substantially white light reflection and have a low stress AR coating and are ideally suited for optical lenses made using a molding procedure which provides a low stress lens substrate. In one aspect the method uses special coating compositions with one being a high index of refraction composition and the other being a low index of refraction composition. In another aspect a method is also disclosed using an optical monitor in conjunction with a conventional vapor deposition apparatus whereby an optical reference lens is used and a particular light frequency of reflected light is measured and this measurement is then used to determine when the desired optical coating is achieved. In a still further aspect the method also preferably calculates the optical thickness of each layer using a specific ratio of blue to green to red colors in the reflected light. The stress of the AR coating is also controlled by adjusting the optical thickness for each layer, if necessary, to minimize the difference in the tensile stresses and compressive stresses between low index/high index layers.
