Dynamic scan stage with large transmitted light

With the KDT600 Steinmeyer Mechatronik offers a large XY scan stage for fast scanning tasks, which can be used to examine biological or medical samples with high precision within a very short time. Even applications with a large number of samples and high-throughput processes require only a few loading cycles. Up to 12 well plates can be placed above the exceptionally large transmitted light of 400 mm with a travel distance of 350 mm. Transillumination of samples from below ensures perfect screening of bioreactions.

Scan table with fast positioning system

By using polished cross roller guides as well as ground stage plates, a repeatability of ±0.15 µm in straightness and flatness is achieved. Thanks to this high precision, only minor refocusing is required even for optics with a very short focus length. The ironless linear motor guarantees a sensitive drive without any disturbing influence on the process parameters. At the same time, the linear motor ensures high dynamics. Accelerations up to 3 m/s² and top speeds of 500 mm/s guarantee short scan times, extremely fast scan results are also achieved in start-stop mode. For equal acceleration values in X and Y, dual motors can optionally be used in the lower axis. The internal feedback system with 0.1-µm resolution and therefore possible positioning steps of 0.3 µm also allows the use of optics with the highest resolutions when using micro-wells.

Air bearing table replacement

The KDT600 is designed for maximum repeatability and achieves accuracies through compensation that were previously reserved exclusively for air bearing systems. However, it is significantly more cost-effective with comparable performance. This is particularly beneficial for applications in the life science and biotech sectors, as well as for active ingredient screening in the pharmaceutical industry. Clean room requirements are met, and a nickel coating is optionally available for surfaces that can be disinfected. When servicing is required, the table can be easily separated from the housed cable guide. This shortens maintenance and facilitates integration. Source: Steinmeyer Mechatronics.
