Enjoy great orientation skills: Automatic laser alignment

A very important but also complex step when performing AFM measurements is the laser alignment. This can be quite time-consuming, not only but especially for inexperienced users. Therefore, Tosca™ 400 provides a fully automatic laser alignment function: After loading the cantilever onto the actuator body and the actuator body onto the AFM head, the instrument carries out the laser alignment automatically after just two clicks in the control software.

The X-Y scan range of up to 100 μm covers a wide range of applications. The X-Y scan location can be regulated very easily by the click-and-move navigation of the Tosca™ control software. Accurate positioning and scanning of your sample is guaranteed. 

With a Z range of 15 μm, it is possible to acquire surface topographies in such a wide X-Y area and perform roughness analysis on such a large Z scale.

The engagement procedure brings the sample surface in contact with the cantilever. This is one of the most complex procedures when operating an AFM. Tosca™ 400 overcomes this problem by implementing a side-view camera. With the camera you can track the exact position of the cantilever with regards to the surface and move the cantilever close to the surface. Then you can start the automatic engagement procedure in the software and within seconds the cantilever touches the surface of the sample and is ready for scanning. 

Go your own way: Compatible with any kind of cantilever

Go your own way: Compatible with any kind of cantilever

There are many different cantilevers and brands on the market – Tosca™ 400 allows you to use your favorite one. Just put the actuator body and the cantilever into the cantilever exchange tool, slide it back and find the cantilever of your choice in an optimal position for your next measurement. There is no need to use tweezers for positioning the tiny cantilever into position anymore – you now have the perfect tool for fast and safe cantilever exchange. 

Let Tosca™ 400 guide you: State-of-the-art sample navigation

Let Tosca™ 400 guide you: State-of-the-art sample navigation

After loading and initializing Tosca™ 400, you can start an overview image of the whole sample table. With only one mouse-click on the desired position inside the overview image, the instrument navigates the sample to the area of choice for the next measurement. This navigation is also available in the micro view. The navigation is triggered fully automatically by clicking into the picture of the integrated video microscope. In this way you can even navigate to small features very easily.
