DISCOVER WHAT greateyes THE EYE CANʻT SEE XUV Spectroscopy: Phosphor-Screen Camera vs. greateyes XUV camera Many beamlines do work with a scintillator (e.g. a phosphor screen) in front of the camera. Advantage: Cost attractive CMOS cameras can be used (scintillators emit much light) Disadvantage: Photon scattering Direct detection without scintillator: Upgrading to a scientific CCD cameras will increase the system's resolution and sensitivity → additional spectral lines might be discovered Prof. Davide Bleiner, EMPA Switzerland, Department Short Wavelength Plasma Radiation November 2018 greateyes company introduction 17

DISCOVER WHAT greateyes THE EYE CANʻT SEE Soft X-ray and EUV spectroscopy using a laser-plasma source Soft X-ray or EUV spectroscopy using a laser-plasma source is one key application. The application is kind of new as experiments in this spectral range were previously only possible with synchrotron radiation sources. In the image a greateyes GE 2048 512 BI is employed to measure: 1) the emission spectra of the soft X-Ray source (100- 1300 eV) utilising a transmission grating spectrometer 2) beam properties by direct imaging of the beam utilizing a pin hole I.

DISCOVER WHAT greateyes THE EYE CANʻT SEE Fluorescence in vivo Imaging Background: fluorochromes are excited by an external light source ● response: light emission of a different wavelength ● emitted fluorescence can be detected by using a camera ● which is sensitive in the near-infrared spectral range Example: detection of cancer cells in the lymph nodes of rodents. For this purpose, a fluorescence labelled dye is applied intravenously into rats. Typical exposure times are long (>5 minutes) → superior cooling performance of the camera is crucial November 2018 greateyes company introduction 20
