ВµXRF with X-ray optics have been successfully used for applications including small feature evaluation, elemental mapping, film and plating thickness measurement, detection of micro-contamination, evaluation of multi-layered coatings for advanced circuit boards, small particle analysis, and forensics.

Additionally, these optics overcome the limitation of inverse square dependence of X-ray intensity on distance from the source, enabling the development of small size and low power ВµXRF systems for in-line semi-conductor and other materials-based industries and development of remote or portable instruments. Polycapillary and doubly curved crystal focusing X-ray optics offer an alternative means to generate small focal spots with high X-ray flux on the sample surface for ВµXRF applications. Unfortunately, this method blocks a majority of the X-ray flux emitted by the X-ray source resulting in low incident flux on the sample which adversely affects the methodвЂ™s sensitivity for trace elemental analysis. Only the X-rays on-axis with the hole are emitted from the aperture. Conventional ВµXRF instrumentation uses a simple pinhole aperture to restrict the incident beam size on the sample surface. Unlike conventional XRF, which has a typical spatial resolution ranging in diameter from several hundred micrometers up to several millimeters, ВµXRF uses X-ray optics to restrict the excitation beam size or focus the excitation beam to a small spot on the sample surface so that small features on the sample can be analyzed. Like conventional XRF instrumentation, Micro X-ray Fluorescence uses direct X-ray excitation to induce characteristic X-ray fluorescence emission from the sample for elemental analysis. Micro X-ray fluorescence (ВµXRF) is an elemental analysis technique which allows for the examination of very small sample areas.
