METHOD OF MULTIFUNCTIONAL PRECISION OPTICAL SIGHTING GRIDS PRODUCING BY LASER ABLATION WITH START-UP

摘要

FIELD: optics; instrument engineering.;SUBSTANCE: invention relates to optical instrument-making and method of multifunctional optical sighting grids producing. Method includes cleaning of substrate, application of optical scale topology elements on substrate in light grid zone by laser ablation using infrared femtosecond pulse laser, start-up, adjustment, cleaning with organic solvent, application of metal coating from aluminium or silver. Outside grid light zone reference marks are made by laser. Then, points of focusing laser radiation are set by reference marks and collimator grid scale elements topology are applied by laser ablation on metal coating at depth of metal layer.;EFFECT: possibility to produce grids of arbitrary topology, high coefficient of reflection of grid and simplification of manufacturing method.;1 cl
