高通量近红外光谱仪

Acton LS-785系列是棱镜型的光谱仪,光通量高,它具备f/2光学系统和抗反射镀膜棱镜,适合近红外波段的应用。f/2的入射孔径使得LS-785可以完美匹配数值孔径为0.22的光纤 (0.22 NA),其光通量是普通f/4反射型谱仪的4倍。 LS-785的棱镜系统使用了普林斯度仪器顶级的抗反射膜,光栅使用了定制的金膜提高反射率,这使其成为市面上光通量最高的近红外光谱仪。LS-785同样配置了光栅调节台,用户可以使用千分尺精准选择750-1100nm波段的频谱。

LS-785具有以下优点:

  • 高通量f/2光学设计
  • 高透射率光学部件
  • 优秀的成像能力
  • 光栅控制台(千分尺控制)
  • 聚焦微调(千分尺控制)
  • 与普林斯顿仪器相机兼容
  • 强大的64位 LightField

 

LS-785让用户可以缩短采集时间的同时,获得极高的光谱分辨率,适合性能指标高的拉曼光谱。结合普林斯顿仪器最新的深耗尽光谱相机,例如PIXIS或PyLoN系列,LS-785可以提供最高的光通量和采集性能。

LS-785的常用应用包括

  • 拉曼光谱
  • 近红外吸收谱,生物组织研究
  • 多通道谱仪
  • 显微光谱仪
  • 荧光光谱仪
  • 光致发光

Application Notes

NIR Spectroscopy Aids in the Diagnosis of Neonatal Brain Injury
Over the past several years, biomedical researchers and engineers working in labs, hospitals, and universities around the world have developed an extensive set of spectroscopy-based methods — including a new class of noninvasive in vivo techniques utilizing near-infrared spectroscopy (NIRS) — to facilitate the rapid and accurate detection and diagnosis of disease and injury.

Using Raman Spectroscopy to Detect Malignant Changes in Tissues
Accurate, rapid and non-invasive detection and diagnosis of malignant disease in tissues is an important goal of biomedical research. Optical methods, such as diffuse reflectance, fluorescence spectroscopy, and Raman spectroscopy, have all been investigated as ways to attain this goal.

Ultra-High-Speed, Time-Resolved Spontaneous Raman Scattering Spectroscopy in Combustion
The recent use of a new diagnostic apparatus to measure the dynamics of each individual molecular species, as opposed to simply acquire bulk information (e.g., pressure), points to the possibility of performing temperature and frequency analyses of species in combustion.
