| Zusammenfassung: | FIELD: optical industry. ^ SUBSTANCE: mirror can be used when producing optical reflecting systems in lasers and experimental physics. Mirror has transparent dielectric base. Metal coating is applied onto the base. Coating has to nanoparticles, for example, silver nanoparticles, which have plasma resonance at electromagnet radiation frequency. The mirror intends to reflect the radiation. Linear dimensions are far smaller than the radiation wavelength. Nanoparticles are applied uniformly onto surface of the base to cover 15% of its area. Thickness of mirror is reduced to minimal size; size of spot of reflected radiation in focus is reduced. ^ EFFECT: reduced thickness of mirror; improved precision. ^ 3 dwg |
