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.

Name	Beam Sampler 25.4mm Diameter 400-700nm
Weight	0.0050kgs
Standard Coatings Available	No
Guide	Please contact our Sales Division for customized products. (Customized on size, wavelength or R:T, etc.) WEB Reference Catalog Code/W3802 For a guarantee in reflected wavefront error or transmitted wavefront error, please contact our Sales Division with your requests. Wedged types are marked with an arrow on the side of the substrate indicating the thickest point of the wedge.
Remark	-
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.
