As atomic force microscopes continue to enter more and more areas of applications, especially in industry, production processes and quality control, standard AFM systems are often not suitable for the task at hand. For these cases, when you need the AFM to be fully integrated in a process, or your samples are too large for standard setups, Nanosurf offers the unique service of designing and developing custom AFM systems and stages that will allow you to perform your measurements with minimal disruption of your established process.
|Automated XZΘ translation stage|
|Max. traverse path XZ/Θ||250/60 mm / 100°|
|Sample size||max. Ø380 mm x 220 mm|
|Stage size||450 mm x 550 mm x 460 mm|
AFM measurements on large concave or convex samples require the scan head to rotate such that the cantilever approaches the surface under the same angle on every location. Economic full 360° manual rotation of the sample platform and motorized
XZΘ-travel ensures to reach every point on the sample.
This micrometer transfer stage allows the examination of a sample with an inverted optical microscope, where the sample faces down, and with AFM, where the sample faces up. The sample – a glass lens – is fixed in place after the area of interest is located using the optical microscope and then flipped over and transferred to the AFM with a repositioning accuracy of better than 10µm.
|Automated XYZΘΦ translation and goniometer stage|
|Max. traverse path XYZ/ΘΦ||72/46/5 mm / ±5°|
|Sample platform size||75 mm x 50 mm|
|Sample size||max. 75 mm x 50 mm x 13 mm|
Precision alignment stage: two goniometer stages and three highly sensitive force sensors were incorporated to allow automated levelling of a sample plane with respect to the scan head within 0.005°. Humidity control and a custom built cantilever holder were developed to facilitate nano-imprint lithography. LEE, I.-Ning, et al. Large-area scanning probe nanolithography facilitated by automated alignment and its application to substrate fabrication for cell culture studies.
