Plate beamsplitters-Economy grade These Economy Plate Beamsplitters have a single layer dielectric TiO2 beam-splitting coating, without the AR coating on the back. The average ratio split of 30 - 40% is in the visible.  The material is available as large sheets at low cost so other sizes are available at short notice. These beamsplitters are typically used in simple lighting applications.
