How to Protect Museum Quality
Artwork with UV Blocking Glass
UV Blocking Glass acts as a mirror with regard to Ultraviolet light wavelengths (400nm and shorter). UV rays are one of the most significant sources of degradation in museum artwork. As such it is a problem that has prompted much consideration. Since artwork is intended to be seen, it is important that any solution to this problem not obscure visible light (400 – 700nm) wavelengths significantly while blocking or reflecting UV light. Adding an Anti-Reflection coating allows greater clarity in the visible light spectrum by helping to alleviate any inherent reflection in the glass.

However, UVA is much closer to the visible spectrum than UV-B. About 75% of UVA passes through ordinary glass. UVA leads to skin damage and genetic mutations that can lead to cancer. Glass does not protect you from skin damage from the Sun. It affects indoor plants, too. Have you ever taken an indoor plant outside and burned its leaves? This happens because the plant was unaccustomed to the higher levels of UVA found outside, compared with inside a sunny window.
ULTRAVIOLET LONGPASS FILTER GLASS
Recent technological advancements, especially in UV LED technology, have opened a new frontier for applications that harness the power of UV light. However, light often needs to be filtered and controlled to gain desired performance results.Our UV filter glasses have been designed to meet common industry requirements; but we also have the capability to customize glass compositions for emerging technologies and applications.

Our UV filter glasses have been designed to meet common industry requirements; but we also have the capability to customize glass compositions for emerging technologies and applications.
COLORED FILTER GLASS
We have a large portfolio of colored filter glass compositions that are engineered to transmit or absorb light in the ultraviolet (UV), visible, and infrared (IR) regions of the electromagnetic spectrum. New technologies and applications are constantly evolving and frequently require custom filter glass compositions. We operate in a single, integrated manufacturing facility with in-house research and engineering capabilities. This enables us to quickly develop custom glass compositions and to manufacture filter glass that meets the demands of emerging technologies.
Optivex™ Ultraviolet UV Blocking Filter
Optivex™ Ultraviolet UV Blocking Filters are EMF’s branded UV filters used by museums, galleries, art collectors around the world to protect art from harmful UV. Commonly sold in sheets (12″x30″ or 10″x30″), Optivex can be applied directly to lenses or other shaped substrates.
UV filters can be glass, rigid plastic or thin flexible plastic. Glass is used for windows and spotlights as well as for enclosures, such as in picture frames (glazing) and display cases. Plastic panels are used for enclosures, while thin films are used primarily on windows.
