Product features

The 50mm x 50mm cutout Mask coupled with the custom Transparency Viewer, provides a ~100% uniform field  allowing accurate measurement of Light Falloff/Lens shading. This mask cutout of 50mm x 50mm is specially designed to work with Edmond Optics neutral density filters to allow for even greater flexibility in creating desired luminance levels.

The ~8" x 10" Mask is a perfect fit for the Dynamic Range Test Chart, allowing for an easy way to block stray light from interfering with the measurement.
