                  Creating High-Efficiency Anti-reflective coatings by Sol-Gel 
                  technology is a new trend that ASM has been exploring during 
                  those last years. This technology allows to realize good 
                  quality anti-scratch/antireflective coatings by wet process 
                  only, which in returns eliminates the need for very expensive 
                  and complicated vacuum-coating equipments. 
                  
                  
                  Asm has developed a process that creates an Anti-reflective 
                  coating for which the residual colour can be very well 
                  controlled, including a white colour. 
                  
                  
                  The curves here after show the reflectance curves of the 
                  layers achieved on both extruded PC sheets and 
                  injection-moulded PC lenses: 
                  
                  
                     
                  
                  
                  As the treatment has initially been developed for military 
                  applications, it passes very severe norms (MILC675C, MILC14806 
                  &  MILC48497). 
                  
                  
                  The process offers reflectance values of less than 0.5% from 
                  400 to 700 nm. The transmission characteristics are directly 
                  driven by the substrate.

                  ASM has developed equipments that can treat from 100 up to 
                  2000 lenses/hour with such treatments, in a very reproductive 
                  manner.
