FIELD: optical materials.
SUBSTANCE: invention provides composition, whose refractory index can be varied by a simple way and which may manifest sufficiently large refractory index difference and provide stable refractory index configuration and optical material irrespective of conditions of their use and way of refractory index configuration and optical material formation. Composition, in particular, contains: (i) destructible compound, (ii) alcoholate hydrolyzate such as, for example, tetrabutoxytitanium, tetramethoxyzirconium, tetramethoxygermanium, or tetramethoxysilane, or halogen-containing compound such as tetrachlorosilane, and (iii) radiation-sensitive destructor.
EFFECT: achieved preparation of stable refractory index varying optical materials.
