We are pleased to present practical users the first table-top X-ray projection microscope combined with a local composition analyzer. Based on polycapillary optics and innovative technical solutions this device gives unmatched apportunities in X-ray imaging, metrology, and even the sample procession.

Unique combination of features

· Simultaneous X-ray and optical imaging

· Sharp contrast enhancement

· Local composition analysis

Choosing an area of interest on the optical or X-ray image,

You can focus X-rays beam and locally determine

chemical elements with space resolution down to 100 microns.

· Local radiation procession

· Fully automated data acquisition

· Fast expositions (down to 1 s)

· Local composition and structure analysis

· Complete radiation safety

Application examples

Non-destructive visualization of inner structure with space resolution of a few microns is strongly needed in many practical technologies and scientific research. We offer to your attention our latest development in digital X-ray microscopy providing an effective solution of this tusk.

Basic advantages:

· simplicity of sample preparation and observation in air conditions

· sharp contrast enhancement and creation of stereo images

· visualization of dynamic processes

· portable and easy to install construction

Achieved image quality is illustrated by a series of triple pictures (triptychs). Left (A) and right (B) parts of a triptych are standard X-ray images acquired at different spectra. The central one (C) is a true subtraction image received by developed methods.
