X-ray optics
from SIGRAYSigray is offering dedicated x-ray optics for experiments at a synchrotron beamline or for the work with a laboratory based x-ray system.
Further information
Customized synchrotron paraboloidal x-ray mirror lens for high resolution experiments
- High resolution with <0.2 - 5 µm spot size
- Large numerical aperture (enabling 4X higher flux at the sample than a KB mirror)
- High efficiency
- Achromatic focusing, ideal for microbeam applications requiring energy tunability such as x-ray absorption spectroscopy
- Flexibility in beamline design: a small form factor enables up to 4 optics to be used within the same beamline, with each optic designed for a different energy, resolution, etc.
Paraboloidal mirror lens configured to focus x-rays
Sigray has developed a new design for x-ray lenses that has numerous advantages compared to polycap or monocap lens designs.
- Intense flux at the sample, due to a combination of: small point spread function, high transmission efficiency (~80%) and large numerical aperture of the optics
- Highest resolution (<8 µm) spot of any laboratory x-ray optic available
- Spot size is round and symmetric with minimal tails
- Most accurate analytical capabilities for microanalysis due to achromatic focal spot and pencil beam focusing
- Large working distances (up to 50 mm) for maximal experimental flexibility for a wide range of sample types
- Compact form factor further enables detector placement for large solid angle of collection

Applications
Energy | Applications | Sigray advantage over other approaches |
---|---|---|
< 3 keV | Ptychography (0.2 - 3 keV) ARPES (0.5 - 2 keV) PEEM (0.1 - 3 keV) | High NA & efficiency for soft x-rays, larger working distance than zoneplates, and achromatic |
< 20 keV | TXM (0.3 - 20 keV) | Customer-specific design Achromatic, high efficiency |
2-60 keV | µXRF (2 - 30 keV) µXRD (5 - 60 keV) XAFS (2 -20 keV) Super Confocal ** | High flux, high efficieny, compact form factor, and more reasonable working distance than KB mirror ** Super confocal options available upon request for <5 µm resolution (configuration uses a twin paraboloidal lens scheme with multiple advantages over polycapilarry optics) |
A turret of multiple optics can be used within the same beamline, allowing access to one or more of the above techniques (e.g. ARPES, confocal, etc.)
- Focusing x-ray microanalysis (e.g. microXRF, microXRD, protein crystallography)
- Collimated x-ray or parallel beam techniques (e.g. SAXS)
- Line focus (e.g. GISAXS, GIXRD, TXRF, etc.)
