Convert RAY files online for free
The converter easily converts your RAY file to various formats - free and online. No Blender or extra software needed.
The converter also works in reverse, so you can convert other Cad formats to RAY with high quality output.
A .ray file is predominantly associated with Optical Simulation Data, generated by high-end engineering software like Synopsys LightTools or Lambda Research TracePro. These files store the trajectory, intensity, and wavelength data of millions of light rays used to model illumination systems, such as LED headlamps, backlit displays, and solar collectors.
A common issue for .ray files is their intense proprietary lock-in. They are often binary containers designed exclusively for the simulation engine that created them. Viewing a .ray file usually requires a specialized, expensive license (often dongle-protected), making it nearly impossible to share raw results with clients or manufacturers who don't own the specific optical suite. Furthermore, these files can become massive (often gigabytes in size) when storing high-fidelity ray traces, making them unwieldy for email or standard storage.
Occasionally, a .ray file may be a legacy ASCII scene description for older ray tracers like Rayshade or SBT-raytracer. These are plain text files but are mathematically abstract and not viewable as images until rendered.
To make this data usable outside the optical lab, users typically need to convert .ray data into:
Convert.Guru analyzes your RAY file, detects the exact format, and lets you read the text inside.
Users also converted REY, RAR, JPG, ART and FS files.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our RAY converter.
