FR-X Specifications

The Rigaku FR-X is the most intense home laboratory X-ray source available today, providing brightness exceeding some second generation bending magnet synchrotron beamlines. Ideal for many applications requiring a very bright X-ray beam, the FR-X provides the flux you need, where you need it: on your sample.
