◦Uncoated surface of optical parallels or wedged substrates are used as reflection surfaces. The rear surfaces are coated with multi-layer anti-reflection.
◦These products have transmitted beam deviation and ghosting of the rear surface reflections due to the characteristics of plate beamsplitters.
◦Wedged beam samplers with AR coating on the rear surface should be selected to prevent ghosting.
