IOR - Index of Refraction values

For use with 3d modeling / rendering and animation applications

Over the past few years I have been collecting all the IOR (Index of Refraction) values I can find for use in 3d rendering applications. 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. It obviously helps if you know what the correct IOR value is for the type of surface you are trying to re-create. 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, Autodesk Softimage, Maxon Cinema 4D, Next Limit Maxwell, and Strata 3d. Please do not take this list to be a scientifically accurate list. It is for general usage in 3d applications only and not for scientific use.

The first list contains many commonly used materials. The next list is the full complete list of hundreds of materials and it is organized alphabetically by material name. 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. If you are not sure where to use the values in your 3d application, I would first check in the manuals - possibly in a surfacing / texturing / rendering chapter. If you cannot find the information there, I would then see if anyone could help in one of the online support forums for the specific application you use.
