X-ray source VariMax™ DW

VariMax™ DW optic Rigaku VariMax dual-wavelength optic combines two VariMax optics, each designed for a different wavelength selected from Cu, Cr, Mo, Ag or Co radiation. 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. The combination of two VariMax optics uniquely enable crystallographers in their home lab to either use a shorter wavelength for higher resolution data such as Cu radiation or a longer wavelength for SAD phasing attempts such as Cr radiation. Data collected on a single crystal at two different wavelengths also enable MAD phasing works. High flux, adjustable divergence, and dual-wavelength make the dual-wavelength VariMax optic the ideal choice for single crystal diffraction and SAD, MAD phasing experiments in the home lab. Features Graded, multilayer confocal optic with increased length for maximum beam intensity Double-bounce beam geometry for optimum beam purity Patented, continuously adjustable divergence slit assembly to fine-tune the X-ray beam divergence and allow for optimal spot separation Choice of two different wavelengths among Cu, Cr, Mo, Ag and Co radiations
