◦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.

▶For a guarantee in reflected wavefront error or transmitted wavefront error
Attention ▶The Beam Sampler has a reflectance of 5.2% when the material is BK7 and the input beam is unpolarized or circularly polarized.
▶The transmitted beam deviation of a wedged beamsplitter is larger then with a beamsplitter made of an optical parallel.
▶The amount of beam deviation of a beamsplitter depends on thickness of the substrate and the wavelength of the incident angle of the input beam.
▶Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
