dThe Nano-Observer is a flexible and powerful AFM microscope. Designed with the ultimate technologies, it combines performance and ease of use. The USB controller offers a real integrated lock-in for better measurement capability (phase detection, Piezo-Response Mode…).A low-noise laser and a pre-alignment system provide simplicity and high resolution on a compact AFM head. Its intuitive software simplifies all AFM settings to allow quick and safe AFM acquisitions.

 

Compact and robust, the Nano-Observer fulfills the requirements for advanced users or beginners. It avoids laser alignment with the pre-positioned tip system. A top and side view of the tip/sample, combined with vertical motorized control, makes the pre-approach easy. Easy positioning can be done by combining the optical access with the X-Y translation stage.
