Sodium Fluoride is seldom used for its optical properties, these being inferior to calcium fluoride and lithium fluoride, but it has one of the lowest refractive indexes of all materials in the UV, and is generating considerable interest as a detector material in high energy physics RICH (Ring Imaging Cherenkov) counters. Sodium fluoride may also be used as an a/r coating material.
