Resolution test targets from Technologie Manufaktur – produced with the best technology worldwide

All of our resolution test targets are made with high-precision e-beam lithography. The 10 x 10 mm² substrate consists of quartz, offering very broad spectral transmission (DUV-VIS-NIR). A chromium layer with high optical density is applied to the substrate.
The test structures are produced by ablation of the chromium layer, whereby structural sizes down to 100 nm are possible as a result of the e-beam process. At the same time, excellent dimensional tolerances and straightness of the structural edges are ensured. Through ablation of the chromium layer, the structures of the test slide are transparent, while the background is blocked by the remaining chromium layer.

The resolution test targets are embedded in a robust stainless steel support with a standard size of 75×25 mm². For use with a microscope objective a version in available with a 0.17 mm cover glass.

Checkerboard TC-CB50

Our TC-CB50 test target offers a checkerboard with 180×180 fields, each with a size of 50 x 50 µm², and is therefore especially suitable for testing image skew and image field curvature. Furthermore, the very sharp edges of the field allow you, for example, to determine the local image quality of a camera. With our Slanted-Edge software package you can determine modulation transfer functions (MTF).

• Testing image skew and image field curvature
• Determine local image quality
• Determine the MTF with our in-house software package
• Total size 9.0 x 9.0 mm²
• Fields: 50 x 50 µm² each

High-Tech from Technologie Manufaktur: Precision through e-beam lithography

In order to be able to test the resolution of high-end microscopes, resolution test targets must be able to show the smallest and most precise structures. This is not possible using conventional photo-lithographic means.

For this reason, in the manufacture of our resolution test targets we use state-of-the-art e-beam lithography. E-beam lithography is primarily used in the semiconductor industry. The individual structures are written onto the wafer with an electron beam.

Although this next-generation lithography takes longer and is more expensive, it allows incomparable precision in terms of structures.


Manufacturing with electron beam lithography must take place in a clean room, since even a few particles can disrupt the structuring of the chromium layer.
