The optical lens is an optical component used for imaging or industrial use. The lenses produced by Yisu Optoelectronics include field lenses, beam expanders, collimating focusing lenses and other types.

Beam expander: It is a lens assembly that can change the diameter and divergence angle of the laser beam. It can make the laser focusing effect better and play the role of collimation.

Beam expanders have multiple uses: first expand the beam and then focus it to get a smaller focus. The beam expander can improve the collimating characteristics of the beam. They can also be used to reduce the beam diameter in acousto-optic or electro-optic modulators. Using the spatial filter and beam expander together can make the asymmetric spot energy distribution tend to be symmetric and make it more uniform.
