FIELD: physics.
SUBSTANCE: method includes heat treatment and formation of regions with modified optical properties. Heat treatment is carried out before the step of forming microoptical raster and includes forming heat-sealed layers on two opposite surfaces of a plate. The heat-sealed layers are formed by irradiating a plate made of porous optical material with laser radiation, the surface of the plate being in contact with a laser radiation-absorbing plate. After forming a heat-sealed layer on the second surface of the plate, microoptical raster is formed in the same layer. The raster is formed by irradiating the plane of forming regions, which is superimposed with the laser beam focusing plane, with laser radiation.
EFFECT: producing microoptical raster from positive microoptical elements on porous glass plates and higher optical power of microoptical elements in the raster.
