Magnesium Fluoride Micropowder

 MgF2 Micro Powder is a positive uniaxial crystal that has a useful transmission. Because  MgF2 Micro Powder has the highest birefringence in the spectral region from 0.13 to 0.30 Aum of any commonly available crystal, it has been used mostly for retardation plates and polarizing elements designed for use in this region of the spectrum. Although x-ray-induced absorption in the 0.25-gm region of MgF2 Micro Powder has been reported, this material to be electron radiation resistant with respect to color-center formation in the UV. This resistance to electron radiation would make  MgF2 Micro Powder a good material for use in a space environment. For application in any high-quality optical system, the optical designer would need to know the refractive index and/or the birefringence of  MgF2 Micro Powder. Only limited data for these parameters are available in the literature. A prismatic specimen of single-crystal MgF2 micro Powder was obtained from a commercial source. The prism was cut so that the optic axis was perpendicular to the triangular faces and bisected the refracting angle. The refracting angle was -68 deg of arc. The rectangular faces incorporating this angle were 4.1 cm long by 2.9 cm high and were polished flat to /2 fringe of visible radiation.
