长期以来阴极发光成像是地质研究的有力工具。最新的技术说明（technical note）为您讲解大面积高光谱阴极发光成像的采集模式。大面积（large area）光谱采集模式主要用于面积较大标本的阴极发光成像，例如锆石和其他矿物。 为了达到大面积阴极发光成像，特地调整光学模组中的光学器件，故意使狭缝平面中的CL焦点散焦。通过这一技术，我们就可以均匀地收集到较大阴极发光视场（FOV），视场大约~300×200μm2。通过调整狭缝宽度，平衡高效率（HE）和视野大小（与正常CL采集相比）

The new white paper, which demonstrates the possibilities of studying alluvial sapphires from Australia with cathodoluminescence (CL) imaging. This research shows how cathodoluminescence can help to assess crystallisation histories of the precious gemstones and underlying causes for luminescence. While being used for a wide range of geological application, including sedimentary petrology, igneous petrology, metamorphic petrology, crystal growth, and gemstone identification, cathodoluminescence is not a common technique to study natural sapphires. However, it is used on zircons frequently to see zircon growth crystallisation, and due to the color zonation in some sapphires, hyperspectral cathodoluminescence was used (together with laser ablation inductively coupled plasma mass spectrometry) to examine zonation and trace element defects to understand the conditions of sapphire formation. The CL measurements for this research were performed with the SPARC, a cathodoluminescence detector, which was mounted on FEG scanning electron microscope (SEM) from Thermo Fisher Scientific/FEI. The results illustrate a strong correlation between color, trace element concentrations, and spectral CL measurements of sapphires.

While most of the time perovskites are grown in a more traditional shape of thin-films and nanocrystals, it was discovered recently that with the use of carbonate salts perovskite materials can take a large variety of complex 3D shapes.

集成光电子关联（iCLEM），荷兰delmic公司创新发明的一种新技术，在SEM内集成光镜，实现样品同一位置进行荧光光学成像和电子显微成像。该显微方法正在世界范围内广泛应用于癌症研究、海洋生物学、神经科学和细胞生物学。最近这种技术在USGS应用于地质学领域，以深入了解地质材料中的沉积有机质。 在最新发表论文中，美国地质调查局（USGS）使用delmic的iCLEM系统SECOM，对始新世绿河红木区不成熟油页岩和上白垩统塔斯卡卢萨群中油页岩进行了观测研究。结果表明，这种技术非常有效地识别和表征有机纳米孔隙形成的有机物质类型和状态[3]。 有机质的数据很容易用高分辨率扫描电子显微镜（SEM）获得，但研究人员不能单独使用SEM来区分有机质的类型，如干酪根与固体沥青。然而，荧光显微镜的荧光像对于识别页岩油气藏中的有机质非常有用[1]。采用光电关联技术，在一台显微镜上结合这两种技术，地质学家可以获得更多的数据，而无需考虑耗时的样品制备，样品转移、重新导航定位等造成的困难或样品损坏[2]。

自动旋转QWP，LP，软件自动纠正偏差， 直接成像 Light is a transverse electromag- netic wave: the electric and mag- netic fields that compose the light wave always oscillate trans- versely to the propagation direc- tion. Besides color (energy) and momentum (propagation direc- tion), light is also characterized by a polarization which describes in what direction these electro- magnetic fields oscillate. If the electromagnetic oscillations re- main in the same plane, the po- larization is referred to as linear but this plane can also rotate while the wave is propagating. In that case, the polarization is elliptical which can be either left- (anti-clockwise) or right-handed (clockwise) depending on the direction of rotation (circular polarization is a special case of elliptical polarization).
