FIELD: optical instrumentation engineering. SUBSTANCE: method includes operations of deposition of layer of polymer adhesive on optical surface of hologram optical element and placement of cover silicate glass on it with subsequent solidification of polymer adhesive. Composition containing, pre cent by mass: heat-resistant low-molecular synthetic rubber CKTH brand A 84.0-90.0; catalyst K-68 5.0-7.0; epylchorhydrine 5.0-9.0 is used in the capacity of polymer adhesive. EFFECT: facilitated manufacture, improved reliability of protection. 2 tbl
