FRED STRAY LIGHT ANALYSIS
The Importance of Stray Light Analysis in Optical Systems
Stray light can significantly degrade the performance of optical systems by introducing unwanted light into the image path, reducing contrast, and causing artifacts. Effective stray light analysis is crucial in designing high-performance optical systems for various applications such as astronomy, defense, and medical imaging.

Why Stray Light Analysis is Critical:
Enhances Image Quality in Imaging Systems
Stray light can scatter and broaden the point spread function (PSF), leading to reduced modulation transfer function (MTF), which in turn degrades image quality. By performing stray light analysis, you can preserve the sharpness and clarity of images.
Optimizes System Performance
Stray light affects the radiometric accuracy of sensors, which is critical in applications requiring precise measurements. Proper analysis ensures that your optical systems perform at their best.
Component Evaluation and Optimization
Stray light analysis helps in identifying and mitigating the effects of surface roughness, coatings, and other material properties that contribute to scattering. This enables you to choose the best components and processes for your optical systems.
How FRED Software Assists in Analyzing Stray Light
FRED Optical Engineering Software is a state-of-the-art tool used for stray light analysis in opto-mechanical systems. It offers comprehensive features for modeling, simulating, and analyzing stray light effects, making it an essential software for optical engineers.
Key Features of FRED:
- Accurate system modeling can be achieved by using the many scatter models (surface and volume), including the ability to import measured data. In addition to this, the comprehensive library of material data, and multiple coating types (including thin film coatings) produce realistic simulations of light interaction.
- Seamless Import Capabilities: FRED can import optical prescriptions from programs like CODE V or Zemax, ensuring that the geometrical and optical properties of the system are accurately represented. This integration facilitates a smooth workflow for optical engineers.
- Mechanical CAD Model Integration: FRED allows the integration of mechanical CAD models, which is essential for analyzing the impact of structural components like baffles and struts on stray light. This comprehensive approach ensures thorough stray light analysis and optimization of the opto-mechanical system.
- Monte Carlo and Ray Splitting Modes: The FRED user can switch between either Ray Splitting or Monte Carlo methods for the raytrace (and even on a surface-by-surface basis), improving the accuracy and reliability of stray light predictions. This flexibility is critical for the efficient and accurate raytrace of complex optical systems.
- Selection of Analysis Tools: FRED includes a variety of analysis tools to help the user diagnose and quantify stray light contributions. Multiple raypath reports, path-based ray filtering for analyses and ray drawing, and also a tool for investigating the causes of hot spots and artifacts on the detector.
