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.

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.
