XR系列微型光纤光谱仪
微型光谱仪者海洋光学（Ocean Optics）的微型光纤光谱仪目前能测量更宽的波长范围。把XR系列光栅用于USB2000+、 JAZ-EL2000及USB4000后,仅需一台光谱仪就可轻松覆盖~200-1050纳米之间的所有波长。
海洋光学（Ocean Optics）研发的新型XR-1光栅选项克服了在单个微型光谱仪中提供UV-NIR（紫外-近红外）宽测量范围的难题。光栅密度为500条/毫米,性能表现优异,可减少预算开支,无需对原由系统作改动。XR-1光栅现可预置在USB2000+、JAZ-EL2000及USB4000内,也可作为客户定制系统的附加选项。
XR系列光谱仪的光学分辨率为~2.0纳米（FWHM）。海洋光学（Ocean Optics）的阶次滤波器被直接用于探测器上,以免产生二阶和三阶影响。预配置装置上25µm开口可为大部分应用装置提供的光学分辨率。对于同时需要测量UV-VIS及VIS-NIR的安装来说,XR系列光谱仪是单仪器方案的选项,它非常适合于测量那些能够对整个波长范围做出反应的样品,例如太阳辐照度、原子发射谱线测量以及一些等离子应用。
检测器
The XR-Series of Extended Range Spectrometers from Ocean Optics are responsive across a wide spectral range, providing you an optical resolution of ~2.0 nm (FWHM) and the convenience of a single, monolithic spectrometer to cover all wavelengths from ~200-1050 nm.
The XR Option is now available for our USB2000+, Jaz-EL200 and USB4000 Spectrometers and in custom systems.
Special Grating Extends Wavelength Range
The ability to provide UV-NIR coverage in a single miniature spectrometer has always been a challenge and daisy-chaining multiple USB spectrometers is not always practical or convenient.
Enter the XR系列微型光谱仪. Thanks to its new 500 lines/mm groove density grating, we can now offer our flagship spectrometers with broader spectral coverage and good optical resolution. This grating delivers 850 nm of spectral range and is blazed at 250 nm. Because their optical bench designs are not affected, the USB2000+, Jaz-EL200 and USB4000 experience no trade-off in performance with the new grating.
Preconfigured Broad-Range Options
Our XR gratings are integrated into three familiar spectrometers - each preconfigured for general-purpose UV-NIR applications.
