[Data Presentation] A Must-See for Optical Design Professionals! Are you able to identify the causes of stray light?

"Why is this stray light here? The unintended ghost won't disappear..." Here, we will introduce an efficient way to solve such problems.

As products become more high-performance, optical design is becoming increasingly complex and advanced. Are you struggling with performance degradation caused by "unintended light" or "stray light" that is discovered after prototyping? - Unable to identify the causes of ghosting and flaring, leading to an enormous amount of time spent on countermeasures. - Simulation results alone do not allow for a clear judgment on which part or surface is affecting the performance. - Relying on experience and intuition for countermeasures may not lead to fundamental solutions. If any of these apply to you, this document will be helpful. This document introduces the "Raypath function" of the illumination design analysis software "LightTools." It explains a groundbreaking method to identify only the problematic light paths from countless rays emitted from the light source and visualize them in 3D. By determining the root cause of "why this light reaches here?" and implementing accurate countermeasures, you can significantly reduce design revisions. We hope this will assist in improving your company's quality and accelerating development speed.
