产品描述
IRA扫描自相关仪
特点：
50 fs - 250 ps
450-2000 nm
USB连接
该自相关仪设计用于测量脉冲宽度及超快放大器及振荡器产生的超快辐射的近似对比度。
该系统包括光机组件及带USB接口及驱动的电子系统。高斯近似及双曲正割轮廓也是可
以做到的。数据采集与分析软件与Windows完全兼容。

| * - each subrange is covered by an exchangeable optics set (NL crystals, beamsplitters, filters, photodetectors). A set for one of the subranges of the customer's choice is supplied with the unit, additional sets are supplied upon request; the final set of optics and detectors depends on the specifications of the sources to be measured and is discussed with our sales manager upon offering; ** - typical values, depends on input pulse duration and wavelength. |
