What’s new in Mountains 8.1?

Mountains 8.1 surface analysis software is on the horizon and due to be released late spring 2020. This latest version makes forthcoming ISO 21920 profile parameters available, improves display and analysis of multi-channel files, in particular those obtained using scanning probe microscopy (SPM) and adds new tools for force curve analysis. Many other enhancements await users working with profilometers and microscopes.

Get Access To Upcoming ISO 21920 Profile Parameters

Over the last few years working group (WG) 16 of the ISO technical committee (TC) 213 has been revising profile standards in order to bring them into line with ISO 25178 areal parameters.

In advance of their publication in 2021, the new ISO 21920 parameters are already available to Mountains® customers in version 8.1, allowing them to get ready for future changes.

This new standard brings together parameters from other standards, principally ISO 4287 (which will eventually be abandoned), and updates certain older parameters. Other parameters have been “imported” from pre-existing standards on surfaces.

These parameters can be calculated on:

  • a primary profile
  • a waviness profile
  • a roughness profile (see image above)
  • a band-pass profile

“Sampling length” has been renamed “section length”.

ISO 21920 parameters are calculated on the evaluation length, as a single value, without averaging (with the exception of the Xpt, Xp, Xvt, Xv, Xzmax, Xz parameters which are averaged using the values calculated on the defined section lengths).

New Palette Options For Multichannel SPM & Hyperspectral Data

Users working with multichannel data, for example obtained with scanning probe microscopes, can now apply various color palettes to each channel, or to all channels. This new option can be used in both 2D or 3D visualization modes.

Axis settings can be set for each channel in the axis settings dialog.

New composite types of rendering are also available, allowing the addition of colors of different layers. Color palettes are shown in a key to the right of the image.

Extended Tools For Colocalization (correlative analysis)

In version 8.1, it is possible to use Mountains powerful colocalization tools with multi-channel data.

For example, AFM data containing several signals (height, phase etc.) can now be overlaid with data measured using another instrument (scanning electron microscopy, spectroscopy etc.)

In the case of spectroscopy, this new feature allows users to correlate elemental and chemical information about a sample with topography information obtained from another source.

Different channels can now be manipulated independently of each other much more easily, dynamic images can be generated and it’s also possible to extract a multi-channel data set from the results of colocalization.

New Indentation Model For Force Curves

New signal types, including those with no deflection can now be processed. Users can calculate deflection from force if constants are defined in the input file, or by using the built-in calibration tool. The JKR indentation model can now be used.

New options for choosing which signal to display and applying colors to each type of phase have been made available (see image below).

Calculate Parameters On Shell Data

The parameters table study is now available for shell data (freeform surface). Users can display number of points and number of facets. This feature forms the basis of a future toolset for freeform surfaces (shells) which will be developed in subsequent versions.
