Optical System Simulation Software - Rayzen Product Introduction
GMPT, October 2024
Software Introduction
Rayzen is a specialized tool designed for the simulation and design of optical systems, leveraging low-discrepancy sequence Monte Carlo methods, non-sequential forward ray tracing, and expert CAD engine. These advanced techniques enable a detailed analysis of light propagation paths, refraction, reflection, and scattering behaviors within complex optical systems. The software analyzes surface morphology, optical properties of components, and material characteristics to accurately model how these factors influence light behavior.
Rayzen finds extensive application in the following areas:
- Stray Light Analysis in Imaging Systems: Investigating unwanted light paths that can degrade image quality.
- Illumination Distribution in Lighting Systems: Optimizing light distribution patterns for efficiency and desired effects.
- Light Transmission and Extraction in Collection and Guidance Systems: Enhancing the performance of systems designed to gather or direct light.
The software is an indispensable tool for research and development in various fields including imaging and non-imaging optical design, photonic components, photonics system integration, display panels, and optical thin films. Through its comprehensive capabilities, Rayzen supports researchers and engineers in achieving precise and innovative optical solutions.
