Index of Refraction: Range of Values?

[sturn]

as far as i know, when plugged in, SLM 's change index of refraction to accommodate the phase changes happening to the input (light). Is there a range for the possible values of the index of refraction?

you'll have to look in an electro-optics textbook for how the index changes. The index of refraction depends on the shape of the liquid crystal molecules changes when the electric field is applied.
