What is Ansys SPEOS
Ansys SPEOS is an optical simulation software product used to model and analyze illumination and imaging performance in virtual prototypes. It is used by optical engineers and product design teams to evaluate lighting, light guides, sensors, and human-vision-related effects for applications such as automotive lighting, consumer electronics, and display systems. The product focuses on physically based ray tracing and photometric analysis, and it integrates with CAD workflows to support design iteration and validation.
Optical ray-tracing focus
SPEOS is purpose-built for optical and illumination simulation rather than general mechanical CAE. It supports physically based ray tracing to evaluate light distribution, stray light, and optical efficiency. This makes it well-suited for workflows where photometric outputs and visual perception metrics are primary deliverables.
CAD-connected design iteration
SPEOS is commonly used alongside CAD environments to evaluate optical performance as geometry changes. This supports iterative design processes where engineers need to test multiple variants without rebuilding analysis models from scratch. The approach aligns with product development workflows that combine CAD modeling and simulation-driven validation.
Photometric and vision outputs
The software supports analysis outputs relevant to lighting engineering, such as illuminance and luminance distributions and related reporting. These outputs help teams compare designs against internal requirements and external standards-driven targets. It also supports visualization-oriented results that aid communication between engineering and design stakeholders.
Narrower than general CAE
SPEOS addresses optical and illumination problems, but it does not replace broader multiphysics CAE tools for structural, thermal, or fluid analysis. Teams often need additional simulation products to evaluate coupled effects (for example, thermal impacts on optical performance). This can increase toolchain complexity in multidisciplinary programs.
Specialized expertise required
Accurate optical simulation depends on correct material properties, surface finishes, source models, and measurement assumptions. Users typically need optics and photometry knowledge to set up models and interpret results reliably. Organizations without optical engineering experience may face a longer onboarding and validation cycle.
Licensing and compute overhead
Enterprise optical simulation tools can involve higher licensing costs than general-purpose numerical computing or entry-level CAD simulation features. Ray-tracing workloads can also be computationally intensive for high-fidelity models or large design-of-experiment runs. This may require planning for license availability and compute resources during peak design phases.
