The wedge angle and back AR coating of the wedge plate beamsplitter reduces the interference of ghost imaging from the back reflection. The high precision substrate will make sure the reflection and the transmission wavefront error. Golden Way provides various kinds of wedge plate Beamsplitters with multiple R/T ratios.
