Laser Beam Expander - Divergence Adjustable
Divergence-adjustable laser beam expanders add beam divergence adjustment to standard laser beam expanders, and can be used to compensate the divergence angle of the input beam. The beam divergence adjustment uses a sliding lens design, thereby minimizing the beam walk-off effect during collimation adjustment. Union Optic provides divergence-adjustable laser beam expanders in various magnifications, covering wavelengths such as 355nm, 532nm and 1064nm. ★ Composed of multiple lenses ★ Expands the laser beam diameter and compresses the beam divergence angle ★ Adjustable beam divergence angle ★ Sliding lens design reduces beam walk-off ★ Various wavelengths and magnifications available ★ Hard aluminum alloy tube with black anodized surface
