地质晶体中科研检测方案(电镜部件)
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.

纳米光子中极化成像检测方案(电镜部件)
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).

锆石中地质稀有元素检测方案(电镜部件)
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）
