DPSS laser module
Lanics
Transmitted laser beam through a lens is collimated and elliptical dot beam. an user can adjust the beam size by movement of lens group.
The lens called a collimator can’t make an ideal collimated beam.
The collimated beam always have very low divergence angle.
Because LD emits a beam of different divergence angles of vertical and horizontal direction.
The shape of dot has an elliptical beam shape.
