DK Photonics 1570/2000 nm Filter WDW is based on thin-film filter technology and metal bonding micro-optic packaging. This component is used to combine or separate 1570 and 2000nm band signal.
DK Photonics 1570/2000 nm Filter WDW is based on thin-film filter technology and metal bonding micro-optic packaging. This component is used to combine or separate 1570 and 2000nm band signal. The devices combine or separate light at different wavelength in a wide wavelength range. They offer very low insertion loss, low polarization dependence, high isolation and excellent environmental stability. High power handling capability can be achieved through unique pigtail processing and high quality AR coating.
