In microscopy, where the resolution depends on the wavelength of the probing light, soft X-rays can be used to analyze samples that cannot be resolved with visible light microscopes. X-ray microscopy in the water window allows imaging with resolutions in the nanometer regime as well as a high contrast between carbon and oxygen, which is an ideal condition for the tomographic investigation of biological samples in their natural state. We present a Full-Field Laboratory Transmission X-ray Microscope (LTXM) at the Berlin Laboratory for innovative X-ray technologies (BLiX) with a probing radiation energy of 500 eV, provided by a laser-based nitrogen plasma source. The development of laboratory X-ray sources aims to increase the availability of X-ray microscopy to a broader scientific community. We will present the latest measurements carried out on biological samples and the corresponding reconstructed tomograms, which are the key to a more precise and global analysis in various fields of life science.
