The DLI reflectors are made from an electrochemically brightened high purity aluminium substrate coil and start with an anodised base coat which gives a hard support to minimize abrasion damage. The material is then treated under vacuum with specially developed processes to maximise coating adhesion and is vacuum coated with a super pure reflection layer of 99.99% pure aluminium.
These reflection layers are overlaid with a dual layer oxide system tuned for maximum visible reflection enhancement. This serves to increase the overall reflectivity provided by the metallic layers and adds protection against damage.
