Co je to fotometrie<\/h2>\n\n\n

Fotometrie je v\u011bdn\u00ed obor zam\u011b\u0159en\u00fd na m\u011b\u0159en\u00ed a kvantifikaci viditeln\u00e9ho sv\u011btla tak, jak jej vn\u00edm\u00e1 lidsk\u00e9 oko. Pom\u00e1h\u00e1 n\u00e1m porozum\u011bt v\u00fdkonu a charakteristik\u00e1m sv\u011bteln\u00fdch zdroj\u016f a syst\u00e9m\u016f a vyhodnocovat je.<\/p>\n\n\n\n

Fotometrie m\u011b\u0159\u00ed a analyzuje r\u016fzn\u00e9 fotometrick\u00e9 veli\u010diny, v\u010detn\u011b sv\u011bteln\u00e9ho toku, sv\u00edtivosti, osv\u011btlen\u00ed a jasu. Sv\u011bteln\u00fd tok p\u0159edstavuje celkov\u00e9 mno\u017estv\u00ed sv\u011btla vyza\u0159ovan\u00e9ho sv\u011bteln\u00fdm zdrojem a obvykle se m\u011b\u0159\u00ed v lumenech. Sv\u00edtivost naopak kvantifikuje mno\u017estv\u00ed sv\u011btla vyza\u0159ovan\u00e9ho v ur\u010dit\u00e9m sm\u011bru a m\u011b\u0159\u00ed se v kandel\u00e1ch.<\/p>\n
