因为全球生产变光面罩的工厂中只有我们独家能够自己研发和生产UV/IR滤

Because global production darkening mask factories only if we can own an exclusive development and production of UV / IR filters, we need to have a deep understanding of optics and applications can do. This is the other variable optical mask assembly plants and we can not be compared.

Because only we in the global manufacturers of variable light masks can develop and produce UV/IR filters on our own, and we need a deep understanding and application of optics. This is something other light mask assembly plant can't compare with us.

Because only we can develop and produce UV / IR filters by ourselves in the global factories that produce dimming masks, we need to have a deep understanding and application of optics. This is something other dimming mask assembly plants can't compare with us.
