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
The process offers reflectance values of less than 0.5% from
400 to 700 nm. The transmission characteristics are directly
driven by the substrate.
Non treated PC
ASM has developed equipments that can treat from 100 up to
2000 lenses/hour with such treatments, in a very reproductive
