Focusing graded multilayer monochromator

Maximizes intensity on the sample within the total external reflection angle for TXRF

Max-Flux® TXRF optic

Introduced by Rigaku Innovative Technologies in the early 1990’s, graded multilayer monochromators provide increased intensity and decreased background for Total Reflection X-ray Fluorescence Spectrometry. Max-Flux® Optics use graded multilayers, assuring the same X-ray energy diffracts from every point along the surface of the Elliptical 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.

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!
