分类: 近红外光谱(NIR)  发布时间: 2011-01-15 06:59 
The USB4000-VIS-NIR is preconfigured for applications from 350-1000 nm. The USB4000-VIS-NIR features a 3648-element Toshiba linear CCD array for increased signal-to-noise and enhanced electronics for controlling the spectrometer and accessories. The USB4000-VIS-NIR Spectrometer is preconfigured with the DET4-350-1000 detector and order-sorting filter to cover the 350-1000 nm wavelength range. The spectrometer comes with a multi-bandpass order-sorting filter and a 25 µm entrance slit for optical resolution to ~1.5 nm (FWHM). 该光纤光谱仪需要与FIAlab流动注射分析仪配套购买,不单独销售!
