Circular Variable Metallic Neutral Density Filters
from Newport Corporation

The circular variable ND filters allow users to finely tune the power of a transmitted beam, or to split a beam with an arbitrary power ratio easily by simply rotating the filter. Filter OD varies continously with rotation angle. Dual purpoased as variable beamsplitter. Withstands moderate energy. [See More]
