Max-Flux XRD

Max-Flux optics use graded multilayers, assuring the same X-ray energy diffracts from every point along the surface of the parabolic optic. Rigaku’s Osmic coating technology provides results in less than 0.5% d-spacing variation. Such high precision means more flux is available for your experiment.

Max-Flux hardware and housing options

Easy alignment, higher brilliance and improved data quality make the Max-Flux brand of optics the first choice for high-resolution X-ray diffraction, thin film analysis, reflectometry, powder diffraction, texture analysis, stress/strain measurements, total reflection X-ray fluorescence (TXRF) spectroscopy and more.

Max-Flux housing features include:

• Four degrees of freedom: Bragg angle elevation adjustment, tilt adjustment and focal length adjustment
• Direct and reflected beam are easily separated by adjustable slits

Monochromatize while simultaneously achieving one of the following:

• Focus a beam from a line source to a thin line—a significant increase in monochromatic flux density at the focus
• Collimate a beam from a line source to illuminate a specific area
• Focus a parallel beam—a significant increase in monochromatic flux density at the focus

A parallel beam creates symmetrical peak shapes, accurate 2Ө values and removes specimen displacement errors for when used in a diffractometer.

When cross-coupled, two parabolic cylinders will create a parallel beam in two dimensions from a point-focus source or a 2-dimensionally focused spot from a parallel beam

Optical precision is also critical to good performance. Using proprietary technology, standard Max-Flux optics are made within ~10 arcsec of the ideal curve. When the best performance is required, Rigaku applies new Arc)Sec® technology to achieve optical precision of ≤ 4 arcsec! As a 1-dimensional optic, divergence in the axial plane can be controlled through use of a Soller collimator.

Contact Rigaku for a suitable collimator for your application. Rigaku provides excellent housings for aligning Max-Flux optics on your instrument. Housing are available for operation in atmosphere or vacuum, for 40 mm, 60 mm, 80 mm, 100 mm and 120 mm long optics.
