Neutral Density Filter
Neutral Density Filters can be absorptive or reflective. These filters evenly attenuate the transmission across a certain spectrum by absorbing or reflecting non-transmitted light. Hence, they are used in imaging applications to prevent damage or inaccuracy from excessive light for instance in-camera, photometer, and light control applications. These filters are available with us in UV, Visible, NIR, and IR spectral regions and in a range of optical densities (0.1–3).
Don’t limit what you see. Customization may be available for this product to suit your technical requirements. Let us know your required specifications.
