MSE PRO™ Rectangular Metallic Linearly Variable Neutral Density Filters, 3"x1"

MSE supplies offers 3"x1" Rectangular Metallic Linearly Variable Neutral Density Filters. This product is a reflective filter. One side of the filter is coated with Ni-Cr-Fe metal film, and the other side is coated with a broadband anti-reflection film in the visible light region. The transmitted light density is linearly attenuated by absorption and reflection in the visible light region to the near-infrared light region. The light density changes linearly in the direction of the extended edge. Neutral density filters block optical energy through optical density (OD). The higher the optical density (OD), the lower the transmittance. Conversely, the lower the optical density (OD), the higher the transmittance. Due to the absorption characteristics of the metal film, this filter is not suitable for high-intensity laser applications.

MSE Supplies can offer a variety of optical components. Please contact us for customization or bulk orders.
