High Precision Laser Beam Expander 5X

To meet the needs of OEM customers, we have developed this high-precision laser beam expander. Before buying, you need to know its primary functions:
1) If you need a coarse beam, it can help you very well.
2) If you want to see a relatively small laser spot from more than 1 km, a laser beam expander can also achieve that. Under normal circumstances, if you don't use the laser beam expander in a place of more than 1 km, the divergence of the laser will form a super big light spot.
