NDQ: Metalic Neutral Density Filter

NDQ: Metalic Neutral Density Filter

NDQ: Metalic Neutral Density Filter

Moderate power broadband UV neutral density filters with uniform wavelength attenuation; 250 - 2500 nm. With minimal variation in attenuation with wavelength over a broad wavelength band, these UV filters coated with Inconel metal alloy on fused silica offer dependable performance for moderate power applications. They are available in a wide range of OD's and sizes for use at wavelengths from 250 - 2500 nm.
