High-Magnification Beam Expander
The high-magnification beam expander continuously enlarges or reduces collimated-beam diameter within selectable ranges of0.5X–2.5X,1X–4X,2X–8X or4X–16X. An optimized low-aberration,air-spaced sliding-lens design provides diffraction-limited performance with minimal effect on expanded-beam M2. Collimation remains constant during zoom,avoiding refocusing. A rear fixed-magnification expander changes the parallel input diameter by a selected factor. Input-divergence fine adjustment locks after alignment for stable collimation. Fixed options are2X,3X,4X,5X,6X,7X and8X.

Beam Expander
U-optic
Lens Material: UV Fused Silica Dimension D: 27 mm Length L: 71 mm
A laser beam expander increases the laser beam diameter to reduce its divergence and is therefore often used in laser ranging or focusing systems. Compared with an unexpanded beam, the expanded beam has lower divergence for long-distance measurements. In laser-processing applications, it can also be focused to obtain a smaller spot with higher power density. U-optic offers beam expanders with various magnifications for wavelengths including 355nm, 532nm, 633nm and 1064nm.

This beam expander is for CO2 laser systems. Beam expanders enlarge beam diameter and reduce divergence for long-range illumination/projection and focusing. Divergence varies inversely with expansion ratio, and an expanded beam can focus to a smaller spot. Magnification is the beam-diameter ratio. The output beam-parameter product is approximately constant: expanding waist radius by x reduces divergence to 1/x. Reducing divergence is collimation; spot size times divergence is an optical invariant. It does not improve beam quality, described here as the product of waist radius and divergence, because the waist/spot grows as divergence shrinks. Laser markers often combine expanders with flat-field focusing lenses.
