LIGHTPATH® GRADIUM® 透镜

GRADIUM®透镜利用生产的轴向倾斜玻璃镜片来改进透镜的性能，加工过程是把几个SF层的玻璃镜片变成一个可逐渐改变折射率的单一的玻璃镜片，折射率从前表面到后表面大概可以改变0.15，折射率的变化能够校正系统像差，特别是在无限远/有限远成像应用中球差以及像面弯曲的校正。GRADIUM® lenses are ideal for laser focusing applications, providing smaller spot sizes compared to the standard PCX counterpart. Two broadband antireflection coating options are available that cover a large range of visible and near-infrared laser wavelengths. For OEM and high volume coating options; please contact our Applications Engineering Department to discuss your requirements.
