TECHSPEC® 超快薄型平凸 (PCX) 透镜采用超薄中心厚度设计,以便为超快激光脉冲提供低群延迟色散 (GDD)。TECHSPEC® 超快薄型平凸 (PCX) 透镜特别适合集合和聚焦来自超快激光源及其相应谐波(包括 Ti:sapphire和Nd:YAG),以及钬和铥激光器的光线。这些超快薄型 PCX 透镜提供标准尺寸,有效焦距从 50mm 到 2000mm。
IR grade fused silica differs from UV grade fused silica by its reduced amount of OH- ions, resulting in higher transmission throughout the NIR spectrum and reduction of transmission in the UV spectrum.
