Perk\u016fv dalekohled s prim\u00e1rn\u00edm zrcadlem o pr\u016fm\u011bru 2 metry je nejv\u011bt\u0161\u00edm optick\u00fdm astronomick\u00fdm p\u0159\u00edstrojem pro v\u00fdzkum hv\u011bzd a extrasol\u00e1rn\u00edch planet v \u010cesk\u00e9 republice. Dalekohled je v sou\u010dasnosti vybaven jedno\u0159\u00e1dov\u00fdm spektrografem, e\u0161eletov\u00fdm spektrografem a fotometrickou kamerou.<\/p>\n\n\n\n

Teleskop je v \u010dinnosti od roku 1967 a stal se n\u00e1rodn\u00edm p\u0159\u00edstrojem astrofyzik\u00e1ln\u00edho v\u00fdzkumu.<\/b><\/p>\n\n\n\n

Optick\u00e1 konfigurace byla kompletn\u011b zm\u011bn\u011bna, co\u017e p\u0159ineslo zv\u00fd\u0161en\u00ed efektivity optick\u00e9ho syst\u00e9mu.

Hlavn\u00edm vylep\u0161en\u00edm byla instalace optick\u00fdch vl\u00e1ken vedouc\u00edch z prim\u00e1rn\u00edho ohniska do spektrograf\u016f. Sou\u010dasn\u00fd teleskop tak vyu\u017e\u00edv\u00e1 pouze jednu odraznou plochu (prim\u00e1rn\u00ed zrcadlo o pr\u016fm\u011bru 2 m) m\u00edsto \u010dty\u0159 zrcadel v minulosti. D\u00edky tomuto vylep\u0161en\u00ed bylo dosa\u017eeno vy\u0161\u0161\u00ed efektivity pozorov\u00e1n\u00ed a je tak\u00e9 mo\u017en\u00e9 pozorovat slab\u0161\u00ed zdroje. Roz\u0161\u00ed\u0159ila se tak\u00e9 \u0161k\u00e1la pozorovac\u00edch program\u016f, kter\u00e9 je mo\u017en\u00e9 s upraven\u00fdm p\u0159\u00edstrojem realizovat.<\/p>\n\n\n\n
