Refractive Index Database

Who dont know this problem: you need something urgent but you have to spend two hours until you have found it. In optics, knowing the refractive index of a material at a certain wavelength could be such a problem. The long solution is to search a book or a paper which helps you to calculate the refractive index, the short solution...

...is going to RefractiveIndex.INFO



created and maintained by Mikhail Polyanskiy. The Database is very extensive and includes:

Crystals/ Metals/ Liquids/ Gases/ Glasses/ Optical Glasses/ Plastics/ Liquid Crystals and even Metamaterials.

Simple choose the material and enter the desired wavelength. But you can do more as only calculating the refractive index. You can choose too from the optical property caculator things like:

reflection coefficient/ Abbe number/ Brewster´s angle/ critical angle or chromatic dispersion.

Simple things, but it save a lot of time. Enjoy!
