Hybrid Lens Simulation

[August 09, 2019]
We analyze in particular how to exploit the dispersion property of diffractive optics to correct chromatic aberration. Since the Summer Release 2019, VirtualLab Fusion supports the import of Binary 2 surfaces from Zemax OpticStudio®, a feature that facilitates a convenient workflow for the analysis of such hybrid lens systems.
[August 09, 2019]

Hybrid optical lenses with both refractive and diffractive surfaces have already proved useful in many applications. As an example, we showcase a hybrid eyepiece with just such a construction, i.e. it consists of both refractive and diffractive surfaces. We analyze in particular how to exploit the dispersion property of diffractive optics to correct chromatic aberration. Since the Summer Release 2019, VirtualLab Fusion supports the import of Binary 2 surfaces from Zemax OpticStudio®, a feature that facilitates a convenient workflow for the analysis of such hybrid lens systems.

Cross-platform Optical Modeling and Design

[August 04, 2019]
The physical optics software VirtualLab Fusion is constructed as a platform to combine different in-built and customized field solvers to enable fast physical-optics simulation and design with ray tracing naturally embedded. This multi-solver concept is complemented by the possibility to use a cross-platform approach, where VirtualLab Fusion is accessed externally.

The physical optics software VirtualLab Fusion is constructed as a platform to combine different in-built and customized field solvers to enable fast physical-optics simulation and design with ray tracing naturally embedded. This multi-solver concept is complemented by the possibility to use a cross-platform approach, where VirtualLab Fusion is accessed externally. In two examples we demonstrate an interaction with Matlab and Python. In this way, tools and algorithms from other programs or programming languages can be used to extend the options for simulation, optimization, design and post-processing.

Binary Grating Design Workflow

[July 22, 2019]
VirtualLab Fusion with its inbuilt Fourier modal method and different optimization algorithms, provides a complete user-friendly design workflow for binary gratings.
[July 22, 2019]

Binary gratings, with either straight or slanted side walls, have turned out to be the key components in many optical applications. Thanks to the advances in e.g. nanoimprint technology, the fabrication of this type of gratings with small, critical dimensions has become feasible. VirtualLab Fusion, with its inbuilt Fourier modal method (FMM, also known as RCWA) and different optimization algorithms, provides a complete user-friendly design workflow for binary gratings that also includes the subsequent analysis of fabrication errors, like rounded-edge effects.

Complete Workflow for the Design and Analysis of Diffractive Lenses

[July 11, 2019]
VirtualLab Fusion, with its Summer Release 2019, provides a complete workflow for the design and analysis of diffractive lenses.
[July 11, 2019]

Diffractive lenses show great potential in various modern optical applications. VirtualLab Fusion, with its Summer Release 2019, provides a complete workflow for the design and analysis of diffractive lenses. It starts with the functional design of the wavefront phase response, which can also, alternatively, be imported from e.g. Zemax OpticStudio®, then includes the actual microstructured lens surface into the modeling, and supports the export of the lens structure for fabrication. As an example, the design and analysis of an intraocular lens is shown.

Ultrashort Pulses Modeling

[July 05, 2019]
For ultrashort pulse applications it is important to understand the mechanism of pulse broadening, and even to control it. As examples, we demonstrate how material dispersion and diffraction gratings can affect the pulse behavior.
[July 05, 2019]

Ultrashort laser pulses show a potential for high-precision material processing. However, such pulses may broaden due to the wide spectrum that corresponds to the ultrashort temporal duration. For ultrashort pulse applications it is important to understand the mechanism of pulse broadening, and even to control it. As examples, we demonstrate how material dispersion and diffraction gratings can affect the pulse behavior.

Modeling of Optical Etalons

[June 21, 2019]
The non-sequential field tracing technique in VirtualLab Fusion enables the accurate modeling of different types of etalons, with either planar or curved surfaces and coatings.
[June 21, 2019]

Optical etalons, in the simple structure of a transparent plate, can form Fabry-Pérot resonators and therefore be used for spectral and/or angular selection. The non-sequential field tracing technique in VirtualLab Fusion enables the accurate modeling of different types of etalons, with either planar or curved surfaces and coatings. As a typical application, we demonstrate the optical setup for the examination of sodium D lines with an etalon as the key component.
