Velox is new again! AI Tilt helps you easily rotate the belt shaft!-Chemical Instrument Network

The data acquisition and processing software Velox for Thermo Fisher transmission electron microscopy has been released in version 3.19! This update brings a comprehensive upgrade in intelligence and user experience, making data collection and analysis more efficient and intuitive!

Here is a quick overview of the highlights:

New AI Tilt features:AI driven automatic tilting belt shaft function. (Paid upgrade option)

New Velox Lite icon design:Velox Lite has made a fresh debut, with clearer visuals and more intuitive recognition.

Custom annotation style:Support maintaining personalized annotation style.

More flexible image export:Added grayscale export option, effectively reducing file size while ensuring image quality.

Interface optimization:Uniformly block the "Beam Blank" button and move it to the SmartCam interface.

Display layout optimization:InDPCWhen using SmartCam in mode, the display is smoother.

Increased data collection:Support saving reference images for spectral imaging.

Analysis data increase:FalconThe dose of the series camera can be displayed in real-time in the data column.

Filter processing enhancement:The updated Wiener algorithm supports non square images.

Iliad EELS module has undergone multiple improvements:Real time status bar updates for sample thickness, multiple EELS optimization fitting, and enhanced ELLS+EDS functionality.

Below is a detailed introduction to the Velox update:

New AI Tilt feature

The AI driven automatic tilt belt axis function easily achieves high-precision and automated tilt operations, freeing hands and making data collection more intelligent!
Suitable for SmartCam andCetaThe camera has been optimized for common STEM modes.
When called, Velox will indicate the tilt direction of the nearest crystal band axis through a green arrow, which is calculated by AI. Once confirmed by the user, the tilt will be automatically executed.
This feature is an optional software.

Custom annotation style

The new interface allows you to directly change the annotation style in the toolbar of the processing window.
Support saving personalized annotation styles for easy reuse in the future.
Click once to change multiple annotation styles.
Velox Lite is also compatible with this feature.

More flexible image export

Added "Save as Grayscale" option, suitable for JPEG, PNG, 8-bit TIFF formats.
For 8-bit TIFF files, this option can significantly reduce the size of the generated file.
Velox can now also import 16 bit TIFF files created by Velox.

Interface optimization

Uniformly block the "Beam Blank" button and move it to the SmartCam interface.

Display layout optimization

Especially when using SmartCam in DPC mode, the display is smoother.

Increased data collection

Support saving reference images for spectral imaging.

Increase in analysis data

Previously, Falcon camera doses were only visible in Velox's "Object Properties"
Now, Falcon camera dose and detector dose can be displayed in real-time in the data bar.

Filter processing enhancement

The updated Wiener algorithm supports non square images.
As a low-pass filter, it suppresses the background in FFT.

Figure 9 Updated Wiener Algorithm

Iliad EELS module has multiple improvements: real-time status bar updates for sample thickness, multiple EELS optimization fitting, and enhanced ELLS+EDS functionality

In the EELS real-time view, when the zero loss peak (ZLP) is included in the spectral line range, the calculated thickness value will be displayed in the status bar of the acquisition window.
In the processing window, the thickness values of all selected areas and the full width at half maximum (FWHM) of ZLP are now displayed in the experimental log.

Figure 10.1 Thickness Status Bar Update

The optimized fitting options have optimized the fitting of each element peak. Improved fitting of energy band edges and alignment of zero loss peaks, resulting in improved resolution.
When EELS and EDS acquisition modes are enabled, the real-time view displays two signals, and the settings are independent of each other.
When selecting the appropriate option from the right-click menu, the data used for each element distribution map in the image browser can be displayed.
