   6. Extended Depth of Focus to get crisp indentation images
   7. Built-in Self Calibration tools
   8. Flexible reporting format
7. Dual cantilever flexure indentation mechanism draws inspiration from compliant mechanisms. Carved out of a single metal block, backlash errors are reduced to a minimum. Higher rotational stiffness is ensured by double cantilever which minimises roll. Perfectly straight motion of the flexure ensures Yaw & Roll errors are negligible, which is essential to make sure the indenter tip is always perpendicular to the sample surface

DeepSense Software

DeepSense, the user-friendly interface developed for DeepIndent allows the automatic acquisition of test data and Real-­time data graphs.
Self-calibration and auto tuning features are robust tools built-­in to enhance the output with minimum intervention of the user.
The inbuilt indent patterns are incorporated to reduce the indent time that helps the user to perform more number of tests in short time
