Beam Expanders 10BE01 have two lenses and are focusable to minimal distance 2 m. In such type beam expander aberrations can be totally compensated only in one point. Depending on customer needs and application we can customize beam expander lenses to compensate aberrations in region of 2 m focus point or for infinity. Beam expanders could be customized for any wavelength from the range of 450-2000 nm. Expansion ratio 2.5 X or 5 X Lenses antireflection coated Focusing range: 2 m to infinity High energy laser beam expansion Specifications Wave length 532 nm (or custom) Input aperture <12 mm Exit aperture < 45 mm Expansion ratio 2.5 X or 5 X Focusing range 2 m to infinity XY-positioning ± 5 mm Tilt angular range ± 4.5 degrees Beam Expanders Housing Material Black anodized aluminium
