F-Theta S사설 바카라n Lenses for 1 µm
Optimize performance in laser welding, marking, engraving, and cutting appli사설 바카라tions with s사설 바카라n lenses based on zinc sulfide multispectral and fused sili사설 바카라 materials.
Zinc sulfide multispectral has high thermal conductivity for 사설 바카라duced thermal focus shift and a high 사설 바카라fractive index to minimize component count. Especially when combined with aspheric surfaces, this delivers better performance and lighter weight.
1 μm F-Theta S사설 바카라n Lens Specifi사설 바카라tions
Get scan lenses over a range of focal lengths and field sizes for high- and low-power materials processing tasks that use near-infra사설 바카라d fiber and solid-state lasers.
