无以伦比的性能与灵活的扩展性

TriVista三级联光谱仪是真正的科研级仪器,具有业界中无以伦比的高性能与高灵活性。TriVista的核心是在Acton SpectraPro系列光谱仪,其本身就具有高分辨率,压制杂散光,成像性能好,可重复性高等优点。基于这样的基础,TriVista三级联谱仪进一步提升性能,追求极致的准确度和可重复性. 

TriVista工作波长从200nm到2.2μm。整个工作范围的光谱分辨率可高达 3pm ,超强的杂散光抑制能力可以保证在拉曼光谱实验中采集到瑞利峰5个波数的数据.

  • 超强的杂散光抑制能力
  • 无以伦比的分辨率
  • 多入口多出口设计
  • 灵活的设计与操作——可以三级联用,也可以单独使用,或者任意选择组合方式

 

最先进的光谱实验需要超高分辨率和超强的杂散光抑制,TriVista专为这样的实验而设计,旨在为科研工作者提供最好的灵活性和最优秀的成谱能力。TriVista三级联光谱既可以在加法模式下操作来达到超高的分辨率,也可以在减法模式下操作以实现优异的杂散光抑制.

用户可利用TriVista多入口多出口的特点来搭建不同的实验,例如UV-Raman和光致发光,可以通过软件来实现两个实验之间的快速切换。 可使用不同的激光波长,同时搭建多台实验设备,使得TriVista成为一个性价比优秀的高端产品.

TriVista的应用包括:

  • 拉曼光谱
  • 光致发光

Single configuration - all three stages can be used simultaneously and independently for three different projects.

TriVista setup

FIg 1B and 1C
Typically, the TriVista is utilized as a double or triple system. When the light beam is passed sequentially through 2 or 3 stages and the gratings coherently move together with very high precision. Some common reasons researchers choose a double or triple system are the high spectral resolution and the high stray light rejection.

These important parameters can be accomplished by utilizing different modes of TriVista operation:

1. Additive mode gives high spectral resolution and high linear dispersion.

2. Subtractive mode gives high stray light rejection.

Resonance Raman Spectroscopy
Instead of fluorescence, some types of colored molecules produce strong Raman scattering at certain conditions. This effect was called Resonance Raman.

X-Ray Spectroscopy
X-ray absorption spectroscopy is an element-specific probe of the local structure of elements in a material.

Stimulated Raman Scattering
Stimulated Raman scattering takes place when an excess of Stokes photons that were previously generated by normal Raman scattering are present or are deliberately added to the excitation beam.
