Superior Performance
All aspects of the Innova electromechanical design have been optimized, from the rigid microscope stage with a short mechanical loop and low thermal drift to the ultra-low noise electronics. The result is a unique combination of high resolution performance and closed-loop positioning.
Innova uses a proprietary ultra-low noise digital closed-loop scan linearization for accurate measurements in all dimensions, regardless of size, offset, speed, or rotation in air and liquid. Superior image quality is achieved from the full 90 micron scan range down to submicron images, with closed-loop noise levels approaching those of openloop operation. In addition, closed-loop scan linearization can be activated and deactivated on-the-fly. This incredible flexibility allows zooming down to atomic resolution on any selected portion of a full size scan - without changing scanner hardware and without withdrawing the probe from the surface. Image rotation, location in the image window, and scan speed do not adversely affect the results.
Highest Resolution Optics
The patented top down optics of the Innova integrate seamlessly with all imaging modes, allowing for a direct view of the cantilever with better than 1 micron resolution, ensuring precise probe positioning on the sample. With the optics positioned entirely inside the protective instrument cover, probe and sample can be viewed at any time while insolating the instrument from the environment. The ergonomic integration of the optics with the microscope also contributes to the ease and accuracy of tip exchange and laser alignment. The user can simply drop in a new tip and swing the optics back into place. The pre-aligned cantilever will always remain in focus. The motorized, software controlled, optical zoom provides a broad range of magnifi cation with an unparalleled resolution. With infinity corrected optics and illumination, the smallest sample feature can be located accurately.
The Innova SPM provides excellent sample access, even when the microscope head is in place, without compromising the rigidity of the mechanical design. The physically open design provides flexibility for custom experiments, e.g., by allowing the easy insertion of electrodes for electrical and electrochemical sample characterization.

Innova Design Features
The Innova head rests kinematically on three independently controlled motors that allow height, pitch and tilt adjustments relative to the sample. This allows much greater user convenience. User defined positions can move the head in sub-micron increments.
Innova has been specifically designed to provide quick and easy tip exchange and alignment. The system comes complete with a universal chip carrier that accepts almost any unmounted cantilever. For even faster and easier tip exchange, our series of precision premounted cantilevers ensure the laser is automatically and precisely focused on the same spot from one tip to the next.
Innova also incorporates numerous additional features that make it one of the most versatile research SPMs, including: Advanced electronics
Modern state-of-the-art electronics provide exceptionally low noise and outstanding closed-loop performance. Innova features a 20 bit DAC architecture for superior piezo control and 8 fast ADCs providing generous data acquisition bandwidth. Two integrated full lock-in amplifiers, enable advanced SPM modes such as scanning capacitance microscopy (SCM) without the need for external hardware or third-party software. Innova is ready for custom experiments with control electronics that provide built-in user access to I/O signals and software that enables flexible signal routing and processing.
Flexible and Versatile Acquisition Software
The completely new SPMlab v7.0 software incorporates a host of features to ensure real world productivity. Direct and intuitive access to all important scan and feedback parameters is combined with extensive realtime signal diagnostics and processing options to accelerate the scan optimization process. Imaging capabilities are enhanced by advanced features like LiftMode and are complemented by several single point spectroscopy modes and an easy to use nanolithography package. Innova comes with an extensive analysis and processing package that integrates seamlessly into the realtime control. Data from partially acquired images can be fully analyzed at any time during the acquisition process without interrupting image acquisition.
