355nm UV beam expander

The JGZOE 355nm beam expander is made from high-purity fused silica, providing excellent UV transmission and outstanding resistance to high-energy laser damage. Designed specifically for 355nm ultraviolet laser applications, it effectively increases the input beam diameter and improves the beam divergence, resulting in significantly enhanced collimation performance.

With a precision optical design and UV-optimized anti-reflection coatings, the JGZOE beam expander delivers a smaller focused spot size and higher focusing accuracy during operation. It is widely used in UV laser marking, micro-machining, precision cutting, and other applications that demand exceptional stability and precision.
