It has been a great pleasure working with attocube to set up two of our cryogenic microwave microscopes. The outstanding scanner/positioner stacks allow us to focus on the science precisely the way when we designed the systems. Many thanks to the highly responsive customer support for helping to choose the right parts for our application and troubleshooting during the operation.

We use attocube linear stages with optical and resistive encoders for positioning of samples relative to high resolution x-ray optics in a Scanning Transmission X-Ray Microscope (STXM). The microscope operates in ultra high vacuum, in magnetic fields and at variable temperature. attocube stages provide the unique capability of high precision long term stability positioning under such conditions, which is crucial for the successful operation of a STXM microscope that serves a broad community of researchers. In addition, we appreciate the excellent customer service and friendly personnel at attocube, always willing to find the solution allowing the client to successfully address a challenge.

attoDRY1000 has quickly become an integral part of the research equipment in our group. The closed-cycle system is easy to operate while providing for excellent stability, short cool down times and low vibration level for optical spectroscopy of solid-state quantum systems. The compatibility with previous versions of CFM-line microscopes and the plug-and-play operation without cryogenic liquids make attoDRY1000 a really attractive alternative to conventional cryogenic spectroscopy in bath cryostat systems.

Thanks to the cryogen free operation and superb mechanical and thermal stability, unattended data acquisition overnight had never been so easy. This is very desirable when we perform photon anti-bunching experiments on a single quantum dot. Without any special effort, we have observed that the dot luminescence intensity remains constant within 14 percent over ten hours.

Our experience working with attocube has been excellent. In our experiment it is crucial to combine high spatial resolution with a large scanning range. The combination scanner/stepper attocube system allows us to position smoothly and precisely within a very large scan volume, and works great. We are also very thankful for how responsive, informative, and helpful the costumer support team has been.

We are pleased with the performance of the attoDRY700. The good mechanical and thermal stability ensures that overnight the selected quantum dot remains within the focus of the objective.
