Optics
1 µm Cover Slides
Protect and increase the lifetime of valuable process optics in materials processing systems based on near-infrared fiber and solid-state lasers.
Many laser cutting, welding, cladding and other materials processing tasks create backspatter and debris which may deposit on lens surfaces lowering performance or leading to damage. Inexpensive, replaceable protective windows provide the solution.
Cover Slide Capabilities
Preserve process optics without reducing performance with fused silica windows that offer high transmission, high damage threshold, and minimal effect on wavefront.
