Vacuum Spectrometer - PGM1000
专著与1- 125 nm
平面光栅单色仪/摄谱仪(PGM-PGS)系列是一种独特的光学设计，耦合了环形镜和畸变校正旋转平面光栅。由于我们的成像校正加技术，每个光栅都经过了特别的设计，与相关的环形镜有一个完美的耦合。 与其他配置方案相比，该方案具有两个主要优点:一是既可用于多通道模式(实平面场)，又可用于单通道(有出口狭缝);其次，光学设计是直的(进、出口臂平行)，出口(无论是检测器还是缝隙)是固定的，使得集成和校准非常容易
PGM/PGS系列光栅有多种选择(主光栅和复型光栅)，覆盖了2 ~ 125 nm范围内的较大的VUV范围。
•影像校正+技术
•轴向光学设计
•主光栅或复制光栅的选择
•运动光栅安装或三个光栅滑块
•专利布局
•高真空兼容
•超过25毫米焦平面的CCD上的最佳图像
•所需空间更小，易于对齐
•可互换的光栅
•真空调焦
•使用掠入射角对光学和正常入射角CCD照明
