Confocal Laser Scanning Biological Microscope from Olympus
Olympus presents its FLUOVIEW FV1000 that features simultaneous laser-light stimulation and imaging by incorporating two laser scanners in a single compact design. This confocal laser scanning microscope delivers efficient and reliable performance together with the high resolution required for multi-dimensional observation of cell and tissue morphology, and precise molecular localization. It incorporates the industry’s first dedicated laser-light stimulation scanner to achieve simultaneous targeted laser stimulation and imaging for real-time visualization of rapid cell responses. Furthermore, it measures the diffusion coefficients of intracellular molecules, quantifying molecular kinetics.
Cathodoluminescence Analysis of Zircons
In this application example, Tescan provides an in-depth geochronological study of zircon grains from North-Western Mongolia. For high resolution imaging MIRA3 field-emission SEM equipped with TESCAN Color CL detector was used. Zircons (ZrSiO4) are ubiquitous in the crust of the Earth and are a common accessory to trace mineral constituent of most granite and felsic igneous rocks. Zircons have low solubility in most melt and fluid compositions and can survive geological processes such as erosion, transport, or high-grade metamorphism. This makes zircon one of the most important minerals for geochronology. Different types of zircon domains are identified by CL imaging and U-Pb dating is then used to determine ages of different zones within the crystal. This helps to recognize various geological processes recorded during the history of the grain.
