- Low Distortion
A CO₂ Beam Expander is a lens assembly that is capable of varying the diameter and divergence of the laser beam. The laser beam emitted from the laser has a certain divergence angle. For laser processing, only the laser beam becomes a collimated (parallel) beam by the adjustment of the beam expander, and a small high-power density spot can be obtained by using the focusing mirror; In laser ranging, the beam collimation must be maximized to achieve the desired long-distance measurement. The beam expander can be used to change the beam diameter for different optical instruments. The filter can be used to make the asymmetric beam distribution become symmetric and to distribute the light energy more evenly. It is mainly used in medical endoscopes, scientific research, special surveillance, stage lighting and other fields.
