Collimating Beam Expander Lens
Beam expander collimating lens Beam expander is a lens component that can change the diameter and divergence angle of the laser beam. The laser beam emitted from the laser has a certain divergence angle. For laser processing, only by adjusting the beam expander to change the laser beam into a collimated (parallel) beam, can the focusing mirror be used to obtain a small high-resolution density spot

Overview
Beam expander collimating lens Beam expander is a lens component that can change the diameter and divergence angle of the laser beam. The laser beam emitted from the laser has a certain divergence angle. For laser processing, only by adjusting the beam expander to change the laser beam into a collimated (parallel) beam, can the focusing mirror be used to obtain a small high-resolution density spot. Application: Laser ranging, changing the beam diameter through a beam expander so that it can be used in different optical instruments. The beam expander can be used with a spatial filter to change the asymmetric beam distribution into a symmetrical distribution, making the energy distribution more uniform.
