Calibration Standards
EUV, X-Ray and visible light calibration standards
Customizable High-Resolution Calibration Standards
The ANT calibration standard was designed for the highest resolution requirements of X-Ray imaging systems with nanoscale features. Available for both soft and hard X-Ray regimes, EUV and optical setups.
Nested Ls or elbows allow for high resolution measurements with guaranteed pitch and efficiency. Down to 15 nm half-pitch on high resolution standard.
Siemen star patterns allow for calibration and accurate comparison of the resolution of optics for X-Ray and other imaging methods.
Applied Nanotools has included the USAF 1951 resolution test chart but with features in nanometres instead of micrometres.
These varying line and spaces are useful for inspection and determining the resolution of a system.
Hard X-ray Calibration Standards are useful for energies above 5000 eV with a standard thickness of 500-600 nm and features down to 25 nm for the HXR-CAL model and 2000 nm gold thickness with features down to 200 nm.
Soft X-ray Calibration Standards are useful for EUV and soft x-ray energies up to 2000 eV with a standard thickness of 200 nm and features down to 25 nm for the SXR-CAL model and down to 15 nm for the ultra-high resolution version.
TEM Calibration Standards are useful for TEM and SEM systems to determine the resolution of a system and other diagnostics. With a 50 nm thick membrane, these standards are useful for transmission and reflection modes.
Custom designs and logos can be added to designs, see pricing for more information on costs.
Our standard frame size is 5 mm x 5 mm. We also offer custom frame sizes. Membrane thickness can be down to 50 nm and silicon carbide membranes are available for those requiring long-lifetime membranes.
The dimensions of the our lightweight aluminum holder are 14 mm tall x 14 mm wide x 3 mm deep and simplify handling of the calibration standards.
