Filtration method


Neutral Density Filters: Absorptive Elliot Scientific Neutral Density Filters attenuate light in the visible spectrum by absorption within the glass. Different filters can be stacked to achieve intermediate densities not available in the standard range. Neutral Density Filters: Reflective Neutral Density Filters: Reflective Elliot Scientific reflective neutral density filters attenuate by a partially reflective vacuum deposited coating. This metallic film offers a broader and more consistent neutral density which is ideal for use in laser projects due to its non-absorption. Filters can be stacked, but care needs to be taken to ensure there are no multiple reflection effects. These can be eliminated by slightly tilting the stack. A useful feature of this type of filter is that it can be used as a beamsplitter.
