Discovering secrets of the ocean: application note on marine microbiology

October 26, 2018

Deep down in the ocean, between and under the layers of the water, the secrets of the life itself are hidden, invisible to the naked eye. Studying marine microbes, which cover more than 70% of the earth and represent the world's largest ecosystem, can reveal information about ocean's chemistry and climate, and maybe even bring us closer to understanding how the life originated on our planet. 

Studying something as tiny as marine microbes can be extremely challenging. Microscopy proves to be a great tool for examining physiological and metabolic states of individual cells. Two types of imaging can be extremely effective. Fluorescence microscopy helps to image the function and provides information regarding metabolism of the organism. On the other hand, it is impossible to get information about ultrastructural composition of the sample. In order to identify cells and different communities of microbes a high resolution imaging, performed by electron microscopy, is required.

New time-resolved cathodoluminescence solution: the LAB Cube

October 16, 2018

We are excited to present a completely new SPARC module: the LAB Cube. This module, which can be fiber-coupled to any standard or new SPARC system, allows to acquire valuable information with time-resolved cathodoluminescence imaging

The module gives the LAB Cube users the freedom to perform lifetime mapping (also known as decay trace) and antibunching experiments (g(2) imaging). These techniques can give insight into intrinsic material properties and can be used for studying the quantum nature of light and single-photon emitters, as well as nanoscale quality and defect analysis. The (nano)materials, which can be studied, include semiconductors for optoelectronics (such as (In)GaN, perovskites, and GaAs), single-photon emitters and rare-earth phosphor materials. 

Watch the video of our application specialist Toon Coenen explaining the possibilities of the LAB Cube.

Studying nanoantennas with hyperspectral cathodoluminescence imaging: new paper

October 01, 2018

A new paper on Imaging Electric and Magnetic Modes and Their Hybridization in Single and Dimer AlGaAs Nanoantennas by the researchers from King’s College London, Université Paris Diderot and University of Brescia was published in the Advanced Optical Materials. This research brings us closer to understanding dielectric nanostructures, and the ways light can be manipulated, which is essential for the development of photonic devices, metamaterials and metasurfaces, as well as for solar cells and sensors.
