今天,中华干燥网小敏给大家介绍一下(光谱)QE65pro海洋光纤光谱仪,以下(光谱)QE65pro海洋光纤光谱仪的内容是小敏网上整理,希望对您有用。
拉曼光谱的理想选择
QE65pro是荧光、拉曼光谱测量的理想选择,尤其是模块化的拉曼光谱仪配置。对于拉曼测量,我们提供900刻线/mm的光栅(#H36),闪耀波长500nm,对于532nm及785nm激光拉曼都具有好的光谱响应。
海洋光纤光谱仪特点:
新光栅选择,用于满足客户波长,光谱范围及杂散光控制需求。新的光学组件设计,用于提高光效率及灵敏度。SMA905及可更换狭缝设计,满足狭缝更换的方便性及好的稳定性。新的光学平台设计以提供更稳定的波长热稳定性。背照式面阵CCD
QE65pro的核心是滨松FFT-CCD探测器,具有*的量子效率(高点90%)及极低的etalon效应。不像线阵CCD,QE65pro允许面阵CCD像素点做并归处理,可以纵向上并归一整列,作为一个像素点,这样可以较大的提高灵敏度及信噪比(>1000:1),并提高处理速度。
而且,TEC制冷(可达-15℃)使得探测器具有更低的噪声,更利于弱光检测,并且积分时间可从8ms到15分钟连续可调,光谱也不会失真变形。
拉曼实验搭建:
QE65pro,拉曼光纤探头,激光器组成的模块化拉曼系统。分叉光纤一端接785nm激光器,另一端接光谱仪。可以用于固体、粉末样品测量,液体样品也可置于比色皿中进行测量。海洋光纤光谱仪参数表:
