Optical Products

Sil'tronix Silicon Technologies produces its own monocrystalline silicon ingot to provide the highest quality to manufacture customized crystals for photonics, synchrotron beamlines, neutron sources, infrared, X-ray…


We are specialized by producing diffraction crystal regarding individual specification or scheme.

To produce a qualitative crystallographic products, pure silicon raw material is used (9N)

The entire production is made internally in order to maintain a reliable and qualitative consistency.

X-Ray Crystals

01.2.jpgOver the past 10 years we produced hundreds of silicon and germanium Crystal X-ray monochromators and mirrors aimed to condition primary X-ray beams or to analyze diffracted X-ray beams in multi-crystal diffraction arrangements. Our silicon crystal blocks include: flat symmetrical of asymmetrical, channel-cut for multiple reflections, symmetrical or asymmetrical. Read more about X-ray crystals

zero diffraction plate for XRD

Silicon sample Holder or also named Zero Background Holder for X-Ray Diffraction (XRD) analysis.

sampleholder.pngOur products are made of semiconductor grade silicon single crystals. They have been designed to be ideal for Rietveld analysis as they present practically no interference lines. The XRD pattern obtained, by using our Sil’tronix crystals as background plate, is very “clean”, so that even at very low-intensity, samples’ Bragg reflections can be easily detected.

Optical windows

Sil'Tronix - Silicon windows.jpgOptical grade Silicon is normally specified with a resistivity of 5 to 40 ohm-cm for best transmission about 10 μm. Silicon windows has a further pass band 30 to 100 microns which is effective only in very high resistivity material. . Read more about optical windows

Porous Silicon (in collaboration with Silimixt)

A porous silicon layer results from an electrochemical etching of a crystalline silicon wafer in a hydrofluoric acid based electrolyte. Various morphologies can be obtained depending on the type, the doping level, the crystalline orientation of the Si wafer and also on the electrolyte composition...

Aln1.jpgAluminum nitride (AlN) is a promising material for many future applications, including blue-ultraviolet LEDs as well as surface acoustic wave (SAW) devices. SAW devices can act as resonators or filters  integrated circuits. They can also be used in wireless sensors operating in harsh environment for instance. As such, they play an essential role in applications ranging from professional radar to mobile wireless systems. Read more about AlN on sapphire






Crystal characterized with X-ray topography from Sil’tronix ST and another supplier.

The topographers are recorded to a 20 keV photon energy and show a 40 mm long section of the 120 mm long crystals installed as a second crystal in a double crystal monochromator.

Both crystals show a very good crystallinity. The Si crystal from Sil’tronix ST is almost free of defects, while the one from the other supplier shows scratches on the surface, most probably due to the polishing process.

Silicon wafer Orientations

Silicon crystals are characterized by an orderly array of their atoms. In monocrystalline crystals, this arrangement is the same wherever the zone within the crystal.
