The transparent polycrystalline optoceramic has single crystallites and at least 95 percent by weight of the single crystallites have a cubic pyrochlore or fluorite structure. The optoceramic is composed of an oxide of stoichiometry:ABDEwherein 0<x<1, 0<y<2, 0<z<1.6 and 3x+4y+5z=8; wherein A is at least one trivalent rare earth cation; B is at least one tetravalent cation; D is at least one pentavalent cation; and E comprises at least one divalent anion. Refractive, diffractive or transmissive optical elements are made with these optoceramics.
