High quality UV Metal coated Neutral Density (ND) Filter
High quality UV Metal coated Neutral Density (ND) Filter
Neutral Density (ND) Filters are often used in imaging systems and laser systems to avoid the damage to camera sensors or other optical components by high power light. ND Filters are designed to reduce transmission of partial light evenly either by absorbing or reflecting the light.
