Fluorescent X-ray film thickness meter

When X-rays drawn from the W target is applied to a metal thin film sample (plating film, etc.), fluorescent X-rays are released according to the elements that make up the sample. The strength is measured separately for each energy (detectioner: proportional meter tube, PIN detector). Because there is a correlation between film thickness and fluorescent X-ray intensity, the film thickness can be determined by the resulting fluorescence X-ray intensity.

It is possible to know the thickness of thin metal films (single-layer film, double-layer film, alloy film) on materials (metal, plastic). Since only X-rays are irradiated with X-rays, in principle, non-destructive measurement (however, depending on the size of the sample, it may not be possible without destructive). The measurable element range is from Ti (titanium) to No. 92 U (Uran).

Since fluorescent X-rays from the measurement part, if there is a shielding material between the detector and the measurement point, it cannot be measured (e.g., the thickness of the inner part of the concave sample).

For combinations containing the same metal (for example, a copper plating film on a brass), the thickness cannot be measured because it is impossible to separate the resulting fluorescence X-rays.
