Microfocus X-ray Fluorescence Spectrometer
"FOCUS-2" On The Base Of Kumakhov Polycapillary Optics

Microfocus X-ray Fluorescence Spectrometer
Analyzer "Focus-2" on the
basis of Kumakhov polycapillary optics is designed for express RFA analysis of the composition and
concentration of chemical elements in solids, loose materials, powders,
liquids, samples precipitated on films and filter paper.

- measurement camera
- optical microscope with video
camera capacity to enable observation of the sample image on the
computer monitor
- x-ray tube complete with power
supply
- x-ray-optical lens with focal
spot size within the range of 50 to 250 micron
- lens alignment assembly
- semiconductor detector

Principle
operation of microfocus x-ray spectrometer "Focus-2" : by moving the stage, the target area on the
sample placed in the measurement chamber for element composition
study is identified. The location of X-ray probe matches the
crosshair of the optical microscope enabling control of the target
point. Two laser beams are also aimed at the same point to provide
for height adjustment of the sample. When those beams match the
microscope’s cross, the target point is aligned for x-ray exposure.
The microfocus x-ray spectrometer "Focus-2" is easy to operate, features full computer
control, no special qualified servicing personnel is required to run
it.
