I can’t find any information on dispersion or temperature for your refractive index liquids.

Due to the number of liquids we carry, we do not have all of the information for every liquid on the site. If you are interested in viscosity, density, temperature, or any other characteristic of our liquids, please contact us via our contact form and select technical question in the topic menu.

I’m trying to match the refractive index of a specific glass. What should I use?

Any of our Standard Series Liquids can be used to match the refractive index of nearly all glasses and plastics. For larger quantities, or a more exact refractive index match to your material, you should use one of our custom blended Immersion or Laser Liquids. We regularly manufacture liquids to match the refractive index of BK7, SF10, BaK, Fused Silica, PMMA, Polycarbonate, Polystyrene, and other glasses and plastics. Because many of our liquids are custom blended, we can (most likely) match the refractive index of your material at any wavelength and temperature. Please contact us via our contact form and select technical question in the topic menu. We can help you determine which liquid is best for your application.
