XR系列微型光纖光譜儀
微型光譜儀者海洋光學(xué)（Ocean Optics）的微型光纖光譜儀目前能測量更寬的波長范圍。把XR系列光柵用于USB2000+、 JAZ-EL2000及USB4000后,僅需一臺光譜儀就可輕松覆蓋~200-1050納米之間的所有波長。
海洋光學(xué)（Ocean Optics）研發(fā)的新型XR-1光柵選項克服了在單個微型光譜儀中提供UV-NIR（紫外-近紅外）寬測量范圍的難題。光柵密度為500條/毫米,性能表現(xiàn)優(yōu)異,可減少預(yù)算開支,無需對原由系統(tǒng)作改動。XR-1光柵現(xiàn)可預(yù)置在USB2000+、JAZ-EL2000及USB4000內(nèi),也可作為客戶定制系統(tǒng)的附加選項。
XR系列光譜儀的光學(xué)分辨率為~2.0納米（FWHM）。海洋光學(xué)（Ocean Optics）的階次濾波器被直接用于探測器上,以免產(chǎn)生二階和三階影響。預(yù)配置裝置上25µm開口可為大部分應(yīng)用裝置提供的光學(xué)分辨率。對于同時需要測量UV-VIS及VIS-NIR的安裝來說,XR系列光譜儀是單儀器方案的選項,它非常適合于測量那些能夠?qū)φ麄€波長范圍做出反應(yīng)的樣品,例如太陽輻照度、原子發(fā)射譜線測量以及一些等離子應(yīng)用。
檢測器
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系列微型光譜儀. 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.
