Beam Sampler 25.4mm Diameter 400-700nm
BS4-25.4C03-10-550
A beam sampler behaves like a plate beamsplitter, it has the ability to reflect approximately 5.2% of the total beam.
◦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.
