High-numerical-aperture optics is key to ultra-fast tomographic microscopy
A novel high-performance custom-made macroscope, dedicated to high-resolution time-resolved X-ray tomographic microscopy, is available for the user community at the TOMCAT beamline since April 2018. The macroscope offers a 4x magnification and has a very high numerical aperture of 0.35. Coupled to the in-house developed GigaFRoST camera, this highly efficient imaging setup enables tomographic investigations with high-temporal and high-spatial resolution: tomographic microscopy studies with a time resolution of 20 Hz and beyond have become possible, unlocking unprecedented possibilities for the tomographic investigation of dynamic processes and radiation-sensitive samples.
