AppNote PX011: VariMax optics for protein single crystal X-ray diffraction


Based on innovative technologies, Rigaku’s VariMax optics deliver more than double the flux of the previous “King of Flux,” the Confocal Max-Flux® Blue. However, while promised by many optics, increased flux for your protein X-ray system is only part of the story. The other factors that lead to improved performance are:

  • Reduced background
  • Optimized divergence
  • Excellent beam shape

Only an optic that addresses all of these concerns will provide the best system performance.
