Import of Microstructure Data via Bitmap and Material Data into VirtualLab Fusion

[March 18, 2021]
In this newsletter, we focus on the import of the height profile of a microstructure and of material data into VirtualLab Fusion.
[March 18, 2021]

In optical modeling it is of necessity to be able to replicate the real world setup as accurately and in as much detail as required. This means that the detail level of the model has to be high enough to account for all relevant effects. The proper setting-up of a digital twin therefore necessitates the import of data and parameters of real elements and materials. This week, we focus on the import of the height profile of a microstructure and of material data into VirtualLab Fusion.

Cross-Platform Optical Modeling and Design with VirtualLab Fusion and Ansys optiSLang

[March 09, 2021]
The optimization of a modern optical system often involves a large number of parameters. This leads to a challenging and numerically demanding task. With the optiSLang Bridge you can directly access the downhill simplex and especially the evolutionary algorithm from optiSLang without leaving VirtualLab Fusion, and the optimization results are also automatically returned in the VirtualLab Fusion session.

The optimization of a modern optical system often involves a large number of parameters. This leads to a challenging and numerically demanding task. For such cases, in addition to the Parametric Optimization feature provided by VirtualLab Fusion, we also offer an interface to the specialized optimization software ANSYS optiSLang, so that several of its advanced optimization algorithms can be applied directly on your optical system. With the optiSLang Bridge (requires a separate license for optiSLang) you can directly access the downhill simplex and especially the evolutionary algorithm from optiSLang without leaving VirtualLab Fusion, and the optimization results are also automatically returned in the VirtualLab Fusion session.

Real vs. Ideal Beam Splitters in a Mach-Zehnder with VirtualLab Fusion

[March 03, 2021]
The Mach-Zehnder interferometer soon became one of the most popular interferometric setups and is still today applied for certain applications. VirtualLab Fusion enables the detailed modeling of the system, including the two 90° phase shifts caused by the real beam splitters.
[March 03, 2021]

The Mach-Zehnder interferometer, invented in the early 1890s, soon became one of the most popular interferometric setups and is still today applied for certain applications. Due to its characteristic well-separated light paths, which are traversed only once, it is a highly configurable instrument (in contrast to e.g. the Michelson interferometer). Two 50:50 beam splitters are used to split a collimated beam into two parts and to subsequently superimpose them back together at the exit. VirtualLab Fusion enables the detailed modeling of the system, including the two 90° phase shifts caused by the real beam splitters.

Customization in VirtualLab Fusion

[February 26, 2021]
This weeks’ newsletter is dedicated to customization via programming. One easy way to configure a customized object is by programming a snippet. Snippets are programmable templates which specify a clear framework for users to generate their objective quickly. For an in-depth understanding of how snippets work, please check out our use cases.
[February 26, 2021]

In VirtualLab Fusion any optical entity is treated as an object. These objects have specific characteristics and may be saved and re-used independently. Among the most known of these objects are the sources, components and detectors. VirtualLab Fusion comes equipped by default with an extensive list of predefined optical objects like a Gaussian source. Despite the versatility of all these "off-the-shelf" components, there are situations in which maybe a specific part of a specialized optical setup cannot be covered with the available predefined objects. The good news is users may tackle this challenge with the help of customization in VirtualLab Fusion.

X-Ray Imaging Systems: Kirkpatrick-Baez Mirrors and Single Grating Interferometer

[February 12, 2021]
In this newsletter, we show two x-ray imaging experiments: (1) Using Kirkpatrick-Baez mirrors to create a nanometer-scale x-ray imaging spot; (2) Illustrating the phase-contrast x-ray imaging principle with a single grating interferometer.
[February 12, 2021]

X-ray imaging is a valuable tool in a wide variety of applications, such as medical imaging and industrial inspection. In VirtualLab Fusion, we have successfully realized several well-known x-ray imaging systems, which can be used to explore the imaging properties of the setup in question, or to illustrate the special x-ray imaging principle. In this newsletter, we show two x-ray imaging experiments: (1) Using Kirkpatrick-Baez mirrors to create a nanometer-scale x-ray imaging spot; (2) Illustrating the phase-contrast x-ray imaging principle with a single grating interferometer.

High-NA Microscopy Systems with Inclusion of Gratings

[February 04, 2021]
Gratings can be applied in microscopy. Ernst Abbe famously used a grating as the sample to investigate the resolution of a microscopy system. We demonstrate by applying different commercial microscopy lenses (Nikon) combined with gratings in VirtualLab Fusion.
[February 04, 2021]

Gratings, as test samples or as components of systems in their own right, can be applied in microscopy. For example, Ernst Abbe famously used a grating as the sample to investigate the resolution of a microscopy system. The magnified image of the grating is obtained at the image plane. Another example is that of Structured Illumination Microscopy (SIM), which uses the demagnified image of the grating at the focal plane for illuminating the fluorescent samples [R. Heintzmann and C. Cremer, SPIE, 1999]. VirtualLab Fusion provides a straightforward way to model such systems in a fully vectorial manner. We demonstrate by applying different commercial microscopy lenses (Nikon) combined with gratings in VirtualLab Fusion.
