Used to parallel the diameter of the linear laser to amplify and amplify the parallel spot after the transmission remains.
1.Products that carry wavelengths or magnifications outside the catalog
2.Various wavelengths of a variety of beam magnification
3.Diopter adjustable, easy to fine tune the parallelism of the outgoing beam
1.The amplification of the linear light of the various laser outputs improves the divergence angle of the laser beam
2.Use a beam expander to get a finer focus spot after focusing
