Ansys SPEOS 

ANSYS SPEOS predicts the illumination and optical performance of systems to save on prototyping time and costs while improving your product’s efficiency.

To design and optimize your optical system quickly and easily, SPEOS combines lighting performance modeling with extensive, dedicated libraries and optimization capabilities. With SPEOS, you can study the interactions of photons with mechanical geometries to quickly create a functional illumination system for your product.

Combined with HPC, SPEOS delivers results quicker with an unprecedented level of accuracy. High-performance computing (HPC) is a game-changer that will help you meet your deadlines without sacrificing accuracy.

SPEOS has an intuitive, comprehensive user interface that helps you increase productivity by computing GPU-based simulation previews in the ANSYS multiphysics ecosystem.

Designing and optimizing your system

Turn on the light in your virtual model and intuitively explore the propagation of light in 3D.

Access ANSYS SpaceClaim Direct Modeler to speed up the design process. The optical part design feature lets you automatically design optical surfaces, light guides and optical lenses.

With SPEOS Live preview for simulation and rendering capabilities, you can design your products interactively. Cut iteration time and speed up your decision-making process by performing simulations right the first time.

Design your digital vehicle 

Validating your system

To match your performance specifications, SPEOS combines powerful light analysis capabilities with illumination evaluation across the electromagnetic spectrum, from UV to near-infrared wavelengths. SPEOS provides a high-fidelity visualization based on human vision capabilities. Deploy these visualizations in virtual reality for a fully immersive review experience.

SPEOS lets you test what-if scenarios quickly and easily. You can improve your product’s performance by choosing the right references from the extensive library. Instead of just complying with international norms and standards, SPEOS helps you to exceed them.

SPEOS light box encapsulates an optical system with all its properties and dependencies in an encrypted file, so that you can share your work with collaborators while keeping intellectual property (IP) totally secure.

Take advantage of the ANSYS platform connecting ANSYS SPEOS with flagship solvers to perform designs of experiments (DOE), design optimization and multiphysics analysis like optical-thermal and optical-mechanical.
