Behind the scenes of Tru Vue®
High-quality, interference-optical anti-reflective glass, or glass for museums, has a firm place in the world of picture frames . It protects sensitive works on paper from dust, dirt, contact and harmful UV radiation. At the same time, it should allow the viewer as unclouded a view of the picture as possible. This means that it must reproduce colours undistorted and reduce reflections as best as possible.
Optical interference anti-reflection coating - What is it?
In short, optical interference coating means that the glass is coated with many thin layers of metal oxide, each of which reflects a different wavelength of light. The visible light waves are then reflected back in such a way that they cancel each other out. This reduces the otherwise distracting reflection in the glass by over 99%. The various layers are only 0.2 micrometers thick in total - a fraction of a human hair (about 500 micrometers).
Behind the Scenes: Tru Vue®
One of the largest manufacturers of museum glass, Tru Vue®, now gives an exclusive insight into the complex production of its high-quality museum glass and Optium Museum Acrylic®. The Tru Vue® plant in Faribault, Minnesota (USA) is state of the art and produces interference optical anti-reflective glass around the clock. In the more than 200m long machine, Tru Vue® (acrylic) glass is coated in a vacuum chamber using so-called magnetron sputtering. The metal atoms are atomized and evenly applied to the pane in several layers without damaging it.
