Carl Zeiss has enhanced Axiovision 4.7 image analysis software with an enhanced topography module that improves surface roughness and height measurements.

For users of stereomicroscopes, new functions simplify and improve the microscopic measurement of surface roughness and the heights of microstructures, resulting in more detailed images.

The roughness values from unfiltered primary profiles, highpass-filtered roughness profiles and lowpass-filtered waviness profiles can now be determined and an unlimited number of profile lines can be drawn and compared in the image.

Height measurements have been improved so users can specify the cut-off wavelength for Gaussian filtering of the calculated height chart.

Height images of stereo image pairs of an object can now be calculated on the stereomicroscope, using a dual phototube and two cameras.

This removes the need for a motorised focus system.

Carl Zeiss’s suggested stereomicroscope system for height measurements is the Stereo Discovery.V8 with dual phototube S, two Axiocam ICc1 digital microscope cameras, the image analysis mini workstation and Axiovision 4.7 with optional topography module.

Other refinements in Axiovision 4.7 include: the Fast Mosaix module, which can scan large surfaces, and the 3D measurement module, which measures, segments and further processes 3D objects.

A diagram view for data lists enables simple preparation of bar and pie charts as well as scatter plots and the ability to export reports into the Microsoft Word-compatible RTF format.
