80% attenuation filters
PRODUCT CATEGORIES
The 80% attenuation filter adopts solid-state optical attenuation technology. The adjustable optical attenuator in the form of air isolation and absorption glass adopts mechanical method to complete the adjustability of attenuation. Now, a small number of solid-state optical attenuation technologies are adopted, such as adjustable diffraction grating technology, MEMS technology, liquid crystal technology, magneto-optical technology, planar optical waveguide technology, etc.
