Moth-eye

WFT has experience working on Moth-eye structures since 1990?  WFT has successfully produced Artificial Motheye structures that have excellent anti-reflectivity across a broad spectrum from a gradient index micro-structured profile.  These micro-structures can be produced on a thin film but are difficult to emboss due to their large surface area.  They are sensitive to finger oils and are not very durable.  They are best used for internal surface that do not come in direct contact with the outside world.  WFT has used these structures primarily for R&D purposes to demonstrate our abilities to originate, tool and reproduce nanometer sized structures on a roll of film.

Artificial Moth-eye structures are produced by recording in photo resist interference fringes generated at the intersection of two coherent laser beams. WFT used this holographic lithography process to produce a moth-eye master tool, which is then used to produce roll-to-roll material.
