The divergence of laser beam emitted from laser crystal is normally
very big. If the working distance of laser is long you have to decrease
the beam divergence. This beam expander series is specially designed
for use with green laser. The different expansion ratio can provide
a small beam diameter at 10m, 20m even at 100m. The lens design
has considered the correction of spherical aberration in order to
get good beam quality at long distance. The lense are not mounted
in lens housing. You can use it based on your system design. Other
expansion ratio is optional based on your request.
