今天，江南全站登陆 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：
