Laser Beam Expanders
Telescope TheoryBeam Expander TheoryApplication 1: Reducing Power DensityApplication 2: Minimizing Beam Diameter at A DistanceApplication 3: Minimizing Focused Spot SizeApplication 4: Compensating For Input Laser Beam VariabilityBeam Expander Selection CriteriaEdmund Optics ProductsBeam expanders increase the beam area quadratically with respect to their magnification without significantly affecting the total energy contained within the beam. This results in a reduction of the beam''s power density and irradiance, which increases the lifetime of laser components, reduces the chances of laser induced damage, and enables the use...See more on edmundoptics RP Photonics
Beam Splitters – optical power splitter, beamsplitter, thin
Beam splitters are devices for splitting a laser beam into two or more beams. There are different types, including polarizing and non-polarizing versions.
