Product Description
Our circular variable neutral density filters are designed to simplify attenuation and beamsplitting in the visible to NIR. The variable attenuation and beamsplitting around a 270° circle is achieved by a thin, reflective aluminum film. A broadband, visible AR coating on the back side allows the filter to be left in the beam path at all times with minimal losses or ghost images. Circular variable ND filters are available with BK 7 substrates for general laboratory use, or UV fused silica substrates for maximum thermal stability.
