Introducing the newly developed W series glass filters suitable for various applications!
The "W Series Sharp Cut Filter" is a new series that replaces the transmission limit wavelength with λτ 0.5 and is based on internal transmission rates. Conventional sharp cut filters were products that complied with domestic standards, but the "W Series" is designed to meet the needs of the global (World) market. 【Features】 ■ Products designed to meet the needs of the global market ■ No angle dependence based on the angle of incidence ■ No changes in transmission and absorption wavelength characteristics ■ Can be cut to any size through post-processing, even with relatively large glass substrates *For more details, please refer to the PDF document or feel free to contact us.
