近赤外用F-θスキャンレンズ
硫化亜鉛製マルチスペクトルレンズおよび融着石英製レンズを採用したスキャンレンズにより、レーザー溶接、マーキング、彫刻、切断用途における性能を最適化します。
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.
