UV Reflective Neutral Density Filters (NDU)

  • UV and visible attenuation
  • Optical Density = log (1/T)

These neutral density filters are made by applying an inconel film to a UV Fused Silica substrate. Inconel has a very neutral transmittance so it does not introduce any spectral distortion while attenuating the beam. Each filter will be provided a transmission scan @ 250nm.
