The x/HP series optics from AXCO:
The world's most intense beams for high-pressure cell microdiffraction.

Our SRA-x/HP series optics for rotating anodes have demonstrated the most intense Mo-Ka (17 keV) microbeam for high-pressure cell diffraction available outside synchrotron beamlines. These optics have facilitated the use of this analysis technique for structure determination from smaller samples than has previously been possible in the lab. Now complemented by our SST-x/HP systems for conventional sealed tubes and MFT-x/HP systems for microfocus tubes, an optics solution to suit your instrumental specifications is both practicable and desirable.

These optics have been designed specifically to produce smaller beam foci at longer output focal lengths than any other optics can achieve - allowing data collection from a smaller sample volume within the DAC cell - at more uniform pressure. Our smallest beams actually permit the study of specimen pressure gradients across the DAC cell.
