in-Situ technology manufacts SILICON NITRIDE WINDOW for Synchrotron radiation which provides highest transmission possible and cleanest window for soft x-ray.
Product Description
The soft x-ray is lacking in the skill of penetrating layer,therefore requiring a smoother, tougher and denser silicon nitride membrane. Silicon nitride windows shall be very stable and no negative effect for its application, combined with economical charge. For applications in x-ray microscopy the windows have the following specifications.

Adapted for Light Source

Our synchrotron radiation silicon nitride window are laid out for?synchrotron radiation soft x-ray observation. If you are not familiar with this field, then you can getting started from previously published papers.?The major applications of synchrotron??radiation soft x-ray test?are in condensed matter physics, materials science, biology and medicine. A large fraction of experiments using such measures probing the structure of matter from the sub-nanometer level of electronic structure to the micrometer and millimeter level important in imaging.

Low Stress Silicon Nitride

The membrane uses ‘low stress’ or LS silicon nitride technology, as opposed to the earlier?stoichiometric nitride layers?window that resulted in stress??but which were under considerable. The low stress?silicon nitride window?are far more iron than the earlier ST nitride layers and therefore the favored option.

High Stress

1000MPa More

Low Stress

250MPa Less

Optical Transparency

Visually one can ‘see through’ the windows if you view them by transmission light microscopy. There has to be some thickness beyond which the optical transparency starts to decline, but even at 200 nm thickness, they are transparent in the visible range of the spectrum. ?Always keep in mind when trying to estimate?the transmission performance of the membrane, optical properties are relative to the absorption edge, ?so please remember the absorption edge?is 13nm. Hence 100 nm thick?membrane?transmittance is about 44% at 13nm; At 12.4nm?the light transmission drops down to about 13%.

Vacuum Compatibility

In-situ technology’s silicon nitride window offers these products as ?vacuum windows carefully. Our existing products which are based upon a same craft has been used this way. Although we don’t have detailed information about the?synchrotron radiation?class products but we can tell some relative data. If the window is assembled into a particular structure, then the window will likely survive a 1 atm situation.

* In-situ technology make NO GUARANTEES about the successful of our synchrotron radiation silicon nitride window in the vacuum test, the membrane MAY be broke in a LITTLE probability.


More features…

  • Silicon nitride window do not react with inorganic acid, except hydrofluoric acid.
  • Some of our silicon nitride window customers find that having some plasma bombard reaction increasing hydrophilic can have some value under some circumstances.
