In the cases where there was a range of IOR values for a specific material I have listed the lower value on the left and the upper range value on the right. The next list is the full complete list of hundreds of materials and it is organized alphabetically by material name. The first group contains many commonly used materials. It is for general usage in 3d applications only and not for scientific use.

Please do not take this list to be a scientifically accurate list. You should be able to use these values in many different 3d applications - such as NewTek Lightwave 3d, Blender 3d, Autodesk 3DS Max, Autodesk Maya, Maxon Cinema 4D, Next Limit Maxwell, The Foundry Modo and Strata 3d. It obviously helps if you know what the correct IOR value is for the type of surface you are trying to re-create. Many 3d applications these days allow you to input actual IOR values in order to achieve a more accurate representation of surfaces during rendering of your 3d models. Over the years I have been collecting IOR (Index of Refraction) values I can find for use in 3d rendering applications. V-Ray renders with both CPU and GPUs to take full advantage of the hardware.

Vray offers a high-performance CPU and GPU rendering engine designed for high-end production. Index of Refraction values (IOR) - For use with 3d modeling / rendering and animation applications Chao group released two versions of Vray for 3Ds Max: V-Ray Next CPU (render uses the power of CPU) and V-Ray Next GPU (render with an or multi GPU).
