Multi-Channel Energy Dispersive Spectroscopy

Through the use of novel imaging approaches that integrate cutting edge advances in both hardware and software, we have developed a new set of research tools for the high throughput compositional analysis of heterogenous biological and synthetic materials.

Harvard’s Wide-Field Electron Optics Laboratory specializes in the development of new Scanning Electron Microscopy imaging techniques for the high-throughput structural and compositional analysis of hierarchically ordered biological materials and synthetic constructs.
