Museum low reflection laminated glass features and principles

Museum low reflection laminated glass features and principles

In museums, it is very important to protect artefacts and artworks. To achieve the desirable display effect, museums need to use low-reflection laminated glass. This article will introduce the characteristics and principles of low-reflection laminated glass used in museums.

Characteristics of Low Reflection Laminated Glass

Low-reflection laminated glass is a kind of laminated glass with special features. It has the following characteristics:

1. Low reflection

Low-reflection laminated glass reduces light reflection and improves light transmission. This means that viewers can see clearer images while avoiding the distraction of light reflections. This characteristic is very important for museums as it reduces viewer interference with the image and improves the display of exhibits.

2. UV protection

Low-reflective laminated glass also prevents the entry of UV rays. UV is a harmful light that can damage the surface of artwork and artefacts. In addition, it accelerates the fading and ageing of colours and reduces the value of exhibits. The use of low-reflective laminated glass prevents these harmful effects, protecting exhibits and extending their life.

3. Safety Protection

Low-reflective laminated glass has good safety performance. This type of laminated glass is composed of multiple layers of glass and PVB film. When the panel encounters external force, even if it breaks, the small fragments will stay on the glass under the protection of PVB film, which reduces the harm to people. This property is important for use in public places such as museums and galleries.

Principle of Low Reflection Laminated Glass

The principle of low-reflection laminated glass utilises the principle of interference of reflected light. When light passes through a glass panel, it splits into two components. One component is reflected on the glass surface and the other component passes through the glass panel. As it passes through the glass panel, these components are again split into two components, one component is reflected on the upper surface and one component passes through the panel below.

This splitting and recombination causes interference of light. If the two components meet at a wavelength and are in opposite phases, they cancel each other out, resulting in attenuation of the light. This light interference phenomenon reduces reflections and increases the brightness of the transmitted light.

To achieve a low-reflection effect, low-reflection laminated glass applies a nano-coating to the glass surface. This coating has two different refractive indices, which allow for the splitting and recombination of light. As light passes through the glass, the coating reduces the amount of reflected light and increases the brightness of the transmitted light. The coating also prevents the entry of UV rays and provides security.

Summary

As a special type of laminated glass, low-reflective laminated glass is widely used in museums. It enhances the display of exhibits and protects from UV light and safety. This article introduces the characteristics and principles of low-reflective laminated glass, hoping that it can be helpful to museum professionals and exhibit protectors.
