IR Wedge plate Beamsplitters

The wedge angle and back AR coating of the wedge plate beamsplitter will reduce the interference of ghost image from the back reflection. The high precision substrate will make sure the reflection and the transmission wavefront error. YZSY Optics provide various kinds of IR wedge plate Beamsplitter for your application.
