Does anyone here have any information regarding this?

Hello Erik,
If you have the filter itself you could calculate it, based on measurements of the critical angle for total internal reflection, using perhaps a laser, accurate angle measurement and the refractive index of air and the relationship that binds them together solved for the index of refraction of the glass that you want to know.
