F-Theta 에볼루션 바카라사이트 Lenses for 1 µm
Optimize performance in laser welding, marking, engraving, and cutting applications with 에볼루션 바카라사이트 lenses based on zinc sulfide multispectral and fused silica materials.
Zinc sulfide multispectral has high thermal conductivity for reduced thermal focus shift and a high refractive index to minimize component count. Especially when combined with aspheric surfaces, this delivers better performance and lighter weight.
