Patterned filter

The demand of patterned filter that has two or more coatings on the same surface is currently increasing,
especially for space telescopes.
It is not easy to use a filter-wheel under specific conditions, e.g. limited space.

We launched the development of pattered filters last year by using our proprietary photolithography technology.
We will challenge the patterned filter which has thick interference films in the future.
