VariMax

Confocal X-ray Optical Assembly

Focuses and monochromatizes an X-ray beam for single crystal X-ray diffraction

Rigaku VariMax optics are the latest generation of Confocal Max-Flux® (CMF) optics. They deliver an intense, monochromatic X-ray beam with adjustable divergence on home X-ray sources.

VariMax Overview

The long length of VariMax optics, compared to other multilayer optics, allows it to capture more of the X-ray beam from the microfocus generator resulting in higher flux. A patented, continuously adjustable divergence slit assembly enables users to fine-tune the X-ray beam divergence for optimal spot separation for different types of crystals.

Different models of the VariMax optics are available for different applications, from the analysis of small and weakly diffracting crystals, to crystals with long unit cell lengths or the need for a specific wavelength for SAD phasing experiments at home. High flux, excellent spectral purity, uniform beam profile, and adjustable divergence make VariMax optics the ideal choice for single crystal diffraction experiments.

Adjustable divergence

Using a novel patented design, divergence in both planes is simultaneously adjusted to achieve the highest useful flux on your sample. The result is an analysis that is both fast and precise.
