CHEM4-UV光谱仪系统
CHEM4-UV-FIBER Spectrophotometer
商品货号：ECS001272
商品品牌：ocean optics
详细介绍

CHEM4-UV-FIBER光谱仪系统类似于一个分光光度计，测量波长覆盖200-850nm的光谱范围，光学分辨率为1.0 nm(FWHM)，能够在1秒钟内获取3648像素的数据。

 

CHEM4-UV-FIBER光谱仪系统是进行相对光强和辐射测量的理想工具。

 

CHEM4-UV-FIBER分光光度计系统由USB4000光谱仪和相关附件组成，来进行吸光率测量。这些可进行吸收测量的附件包括ISS-UV-VIS集成取样系统、一根300μm的抗负感光纤与一个1-cm样品池支架。
