Monolith Lens

CLASER develops a monolith lens for laser beam expander. It is very good to make a very compact laser head, and easy to reduct laser
 divergence angle, especially for eye-safe laser application. It works like
a couple of lens assembly, but our new product has its advantage:
 
◆ Good divergence angle control;
◆ Laser head compact and size reduction;
◆ Easy for assembly.
