UV grade Fused Silica Neutral Density Filters Datasheets

Neutral Density UV Metallic Filter -- FNU00325
from Knight Optical (USA) LLC

0.03 OD Metallic ND Filter.UV grade -25dia. These Metallic Neutral Density Filters attenuate light through reflection rather than absorption as in the glass type of neutral density filter. Metallic Neutral Density Filters consist of a thin layer of nickel-chromium alloy vacuum-deposited on a glass... [See More]

Circular Linear Variable ND Filters
from Newport Corporation

The circular variable ND filters allow users to precisely attenuate or split the power of a transmitted beam by an arbitrary ratio. The density of this filter varies linearly with rotation angle, making it easy to attenuate or split a beam by a precise amount. Filter OD varies linearly with rotation... [See More]
