Product Description
Our absorptive neutral density filters provide broadband attenuation for the visible to near-infrared region. These filters are precision polished for demanding research or OEM applications. Three sizes are available 12.7 and 25.4 mm round and 50.8 mm square. The 25.4 mm diameter and 50.8 mm square filters are permanently marked with the optical density and are available individually or in a set of nine.
