SEAL 355-3/5
3-5W
The Seal-355-3SE & 5SE are newly upgraded models of ultraviolet solid-state lasers, featuring a monolithic structural design that integrates the optical path and external drive circuitry into a single unit. This design significantly enhances the electromagnetic interference (EMI) resistance of the series. Further optimized with a fully sealed enclosure, the lasers effectively prevent external dust ingress while also blocking moisture penetration, ensuring robust humidity resistance. These advancements enable the Seal series to operate reliably in harsh industrial environments.
