IR Neutral Density Filters
Visible/Near Infrared (Ni) Neutral Density Filters – Low Reflectivity
• Ni filters reduce light intensity neutrally throughout the visible and near IR spectrum without affecting color and contrast
• Ni filters can be used with monochrome and color cameras in the visible spectrum
• Ni filters must be used to reduce intensity in infrared applications
