Optical Lamination

A fully laminated window consists of two outer substrates with a sandwich construction of alternating layers of adhesive and other elements, such as mesh and optical films.

Following the assembly of the adhesive and substrate in a clean room, the windows are subjected to a heat and pressure process in an autoclave.

The optically matched adhesive layer provides a fully laminated structure in which the entire surface between layers is bonded. There is no limit to the number of layers or materials that you can incorporate into a laminated window, providing they are optically and mechanically compatible. 

Substrates

Fully laminated windows allow a wide range of substrates. The standard options are: 
Glass, Polycarbonate and Acrylic

The appropriate substrate is selected by matching substrate properties to end-use requirements and cost.

Adhesives

Optical Filters knowledge and experience is required for the optimum selection and processing of the dry film adhesive. At least one layer is required between each solid component in the laminate.

Laminated windows have many advantages in strength, form and function. Applications include:

EMC filters 
Laminated windows can incorporate either a layer of metal mesh or a conductive coating to provide emi shielding for a display.

Security Screens
A laminated window has approximately the same impact resistance as a toughened piece of glass of the same thickness. It offers an impact resistance equivalent to BS6206:1981, which specifies the requirements of glass structures. A significant added benefit of a laminated glass window is the safety aspect. If a laminated window were to shatter, the glass shards would adhere to the adhesive layers rather than scatter out.

Contrast Enhancement filters 
The principal application of color laminations is in contrast enhancement filters. Colors and tints can be added to any type of window by use of a colored substrate or a tint layer. Optical Filter's tint layer technology allows a wide range of options and where necessary, we can selectively color different areas of a window to match multi-function display requirements.

Privacy Filters
View control films are an important addition to laminated windows used on ATMs and public information displays. These privacy filters control the positions from which the display can be viewed.
