使用 Verona 滤光片提高拉曼系统性能

2025年3月9日 作者: IDEX Health & Science

Verona, designed and optimized for Raman applications. Now available in new wavelengths

拉曼光谱和显微镜都是非破坏性分析技术,需要能够从与激光线相邻的弱、非弹性散射光谱中解析信号。这些测量通常面临两个限制:(1)拉曼散射截面很小,需要强的激光和灵敏的检测系统才能获得足够的信号;(2)信噪比进一步受到样品自发荧光等基本固有噪声源的限制

探索 Verona™ 滤光片系列

IDEX Health and Science 了解这些挑战,我们很自豪地宣布,我们的 Semrock 品牌滤光片专为拉曼仪器设计。新 Verona™ 滤光片产品系列的设计充分考虑了您的需求:

  1. 过渡宽度(截止)≤ 0.2% ,更加畅通无阻的信号收集,是我们 Semrock RazorEdge E 级滤光片的两倍
  2. 比我们的 RazorEdge 的系列产品相比,提高了陡度
  3. 低纹波,可提供更佳信噪比,并允许更大程度地收集弱的拉曼光谱特征
  4. 该产品系列现在拥有 532 nm, 633 nm, 785 nm三款产品, 488 nm 即将发布。
  5. 在激光线上深度阻挡 > OD 6,消除激发光的透过
  6. 用于高激光损伤阈值的硬涂层
  7. 凭借我们的 Kola Deep 光谱测量系统,我们提供光谱数据来证明我们的深度阻挡和边缘陡峭性能
  8. 提供 12.5 mm 封装标准尺寸部件和 10 mm 通光孔径,为您的苛刻的应用提供更多空间

Verona 的低纹波提供了更佳的信噪比,允许更大限度地收集弱拉曼光谱特征

Semrock 的长通 Verona™ 滤光片为拉曼应用的激光线附近的深度阻挡提供行业解决方案。Verona只是我们不断发展的拉曼产品线的开始,以适应拉曼市场。我们了解平坦传输对于更大程度地收集弱拉曼信号的重要性,这就是为什么我们提供具有低纹波和更陡边缘的滤光片的原因,这使 Verona 系列成为拉曼的新选择。以行业更佳的过渡宽度推动您从拉曼系统中看到更多。
