Import of Zemax Optical Systems and Export for CAD

[September 12, 2018]
VirtualLab Fusion offers a user-friendly interface with Zemax, with which one can import complete optical systems from Zemax with full three-dimensional position information and glass material definitions. That enables an efficient and flexible workflow for optical designers who have access to both software packages – one optical system analyzed with both Zemax and VirtualLab. On the other side, optical systems and components in VirtualLab can be exported into various computer aided design (CAD) formats, such as IGES and STL, which makes it convenient for possible further fabrication processes.

This enables an efficient and flexible workflow for optical designers who have access to both software packages - one optical system, constructed once, and analyzed with both Zemax and VirtualLab. On another note, optical systems and components in VirtualLab can be exported into various computer-aided design (CAD) formats, such as IGES and STL, which makes it convenient for eventual further fabrication processes.

Panel-Type Source and Its Use in Imaging System Analysis

[September 06, 2018]
Nowadays, panel-type display devices are widely used in different optical system, e.g., image projection systems. The panel-type source in VirtualLab can be used to model the light generated from such display devices conveniently, with direct access to parameters like pixel number and pixel pitch. With the help of the panel-type source, the performance of the projection lenses can be analyzed, by e.g. observing the spot grid distortion in the image plane, or by checking the angular/direction behavior of the system.

Modern display devices (LCD) are widely used in different optical systems, e.g. image projection systems.

The panel-type source in VirtualLab can be used to model the light generated by such display devices conveniently. In order to configure the source a specific number of pixels and pixel pitch can be set. With the help of the panel-type source, the performance of the projection lenses can be analyzed, by e.g. observing the spot grid distortion in the image plane, or by checking the angular/direction behavior of the system.

Scanning Source and Evaluation of F-Theta Scanning Lens

[August 29, 2018]
High-quality scanning systems are of importance for many optical applications, e.g., in laser beam welding, drilling and cutting. Such systems are typically constructed with F-Theta lenses. An F-Theta lens is supposed to focal the beam on the focal plane with a lateral displacement proportional to the scan angle. With the help of the scanning source in VirtualLab, the performance of an F-Theta lens can be analyzed by e.g. measuring the lateral shift and the size of the focal spot under different scan angle.

Modeling of Femtosecond Pulses

[August 01, 2018]
Femtosecond pulses are drawing more and more attentions in modern optical applications, because of their ultrashort temporal duration and the corresponding ultrahigh power. The ultrashort temporal duration also leads to broad spectrums. Such spectral or temporal properties of femtosecond pulses must be properly handled together with their spatial behaviors for the modeling. VirtualLab Fusion provide such a physical-optics simulation platform that is capable of femtosecond pulse modeling.

Design of Refractive Beam Shapers

[July 30, 2018]
Refractive beam shapers are of great help in several laser-related applications. For example, in material processing, the laser beams are often required to have uniform distributions, like top-hat, on the target plane. In VirtualLab, refractive beam shapers can be designed by using a user-friendly workflow, and the design results can be exported into those formats which are ready for fabrication purpose.

Modeling of Microlens Array and Diffraction at Apertures

[July 30, 2018]
Microlens arrays can be found in different applications, such as imaging, wavefront sensing, and so on. With the physical-optics simulation technique in VirtualLab, the working principle of the microlens array, e.g. in the case of wavefront sensing, can be clearly demonstrated, and the performance of such systems can be evaluated efficiently. And, it is worth mentioning that the diffraction effect from the edge of microlenses can be taken into consideration in the simulation.

Evaluation of Fiber Coupling Lenses and Their Design

[July 30, 2018]
How to ensure a high-efficient coupling of light into optical fibers is an important question in all fiber-related applications. In VirtualLab, the focal field behind the coupling lens can be easily calculated with the fast physical optics simulation engine, and by calculating the overlap integral, the fiber coupling efficiency can be evaluated. Additionally, with the parametric optimization, the lens parameter can be designed for customized situations.
