![]() Laminated safety glass Artglass AR 99 Protect with approx. For the very demanding framing of large works, this means a clear plus in stability and flatness of the picture glass. A big advantage of this type: If you want to realize large-format "XL" applications, the material is also available in 4.5 and 6 mm thicknesses. True Vue's Optium Museum Acrylic is usually used in 3 mm thickness. We have specifically selected these thicknesses as the optimum variants for your picture.Įxceptions are the following varieties Optium Museum Acrylic with 3 mm PLEXIGLAS®, Artglass museum glass and Optium Museum Acrylic from True Vue are 3 mm thick also. Normal glass and white glass have a thickness of 3 mm at HALBE. Plexiglas has the mattest, roughest appearance when used with an anti-reflective surface. The single-sided matt normal glass and the safety glass are more strongly structured than the white glass and thus appear slightly less contour-sharp. It is therefore recommended if there is a distance between the image and the glass surface - for example in combination with a 3 mm thick passepartout. So you can make your decision in peace after the purchase.ĭue to its microfine structure, the one-sided matt white glass has the best contour sharpness among this type of glass. So you can simply turn them over in the picture frame and use them either with an anti-reflective effect or with the glossy surface. HALBE anti-reflective glasses are always matt on one side and glossy on the other. This means that the finer the structure of the glass surface, the more perfectly the sharpness of the contours is maintained - while at the same time reducing reflections. Glass experts speak of the gloss value in connection with the contour sharpness of structured, roughened glass surfaces: the higher the gloss value, the finer the structure of the roughened glass surface. The only exception here are anti-reflective glasses: the sharpness of the contours is maintained to one hundred percent, since the reflection reduction is achieved by an invisible coating instead of a roughened glass surface.Īre there any differences in matt glasses? ![]() Disadvantage: With a smooth and shiny glass surface, the viewing suffers from reflections. The highest possible and best contour sharpness is achieved when the surface of the picture glass is smooth, not roughened. It is the optimal solution for unadulterated enjoyment of art and meets the highest demands of museums all over the world. Anti-reflective glass is also suitable for DISTANCE magnetic frames. The glass is completely transparent and the image remains true to the original without any interference. The anti-reflective picture glass - often referred to as glass for museums - reduces the reflections in a different way: The technical term "interference-optically anti-reflective" refers to an optical coating that is achieved by a dipping process: similar to a spectacle lens, the glass surface remains smooth and reflections are reduced by the coating to less than 1%. Interference optically anti-reflective glass Since the effect increases as the distance between the glass and the picture surface increases, frosted glass is not suitable for DISTANCE magnetic frames. Further effects: the luminosity of colours or, for example, glossy areas in pictures or paper are lost to a certain extent. As a result, the image can be viewed glare-free. With one-sided matt glass, the glass surface is roughened by etching the glass: the light is broken by the uneven glass surface, and the glass surface no longer appears glossy but matt. Precisely, there are two types of "anti-reflective glass": This often refers to a picture glass with a matt, slightly textured glass surface. If one wants to reduce the reflections in the glass, one often speaks of "anti-reflective" glass in colloquial language. ![]() ![]() It shows a perfect contour sharpness and is rich in contrasts - but: due to the smooth and shiny surface of the glass, the surrounding space is reflected when the picture is viewed in the glass pane and the joy with the picture is severely disturbed. A glossy glass is the most affordable standard for picture glass. ![]()
