We've Bent Over Backwards To Achieve Flexibility:
The BerMad 2000 offers a variety of operating options including Contact and Non-Contact Mode AFM, as well as STM. With our unique "Jump" Intermittent Contact Mode, you can simultaneously measure the topography and physical properties of the surface/sample. There's also a unique Movie Mode that enables dynamic processes to be studied, with automatic drift compensation.
Open Modular Architecture Provides Room For Expansion:
The control system accommodates a variety of commercial and custom-made heads, operating stepper motors, inertial motors, and piezo motors. A fast DSP control unit with four I/O channels enables simultaneous imaging of normal topography and lateral forces; force-distance curves; and Intermittent Contact Mode with adhesion mapping.
The BerMad Optical & Scanner System Is Worth A Closer Look:
Viewing of the scan region is through a beamsplitter, giving clear optical viewing of the sample. A compact set of microadjusters makes for fast and flexible fine-tuning of the probe and detector.
To permit large scans as well as high-resolution imaging without the need to reposition the sample, the scanning mechanism incorporates two concentric piezo tubes. A scan size of 75 µm (XY) is standard with a Z vertical range of 15 µm. The high resolution scan tube gives an XY range of 5 µm. The use of the concentric PZTs also minimizes thermal drift, so the BerMad's unique Movie Mode imaging can be utilized.
