UV Filters

Asahi Spectra offers variable kinds of precise UV Filters that will surely fit your needs and deliver the solution. We always manifest the measured performance graph if available so that customers can simply understand if you can use it in your application, and that draws the line with the other manufacturers who show only designed data. All our products are carefully tested and measured by lot-base and those data are attached with the products when shipped. We will give you the "safe" products proven with the fact.
