Kvadratni filter 50 x 50 mm v aluminijastem okvirju sodi v držala za kvadratne filtre te mere. Prepušča ultravijolični del spektra, okno sega približno od 320 do 400 nm; prepustnost sledi sistemu UBVRI, kot ga je leta 1990 za digitalne senzorje uskladil M. S. Bessel.\u003c\/p\u003e\u003cp\u003eUporaben je od f\/15 do f\/1,8, z današnjimi kamerami CMOS in starejšimi CCD. Namenjen je fotometriji, torej merjenju sijaja zvezd s kamero; za vizualno opazovanje ni predviden.\u003c\/p\u003e\n\u003ctable class=\"szq-spec\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eOkvir\u003c\/td\u003e\n\u003ctd\u003eFrames\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial okvirja\u003c\/td\u003e\n\u003ctd\u003eAluminium\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNanosi\u003c\/td\u003e\n\u003ctd\u003eReflex-Blocker™\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVelikost filtra\u003c\/td\u003e\n\u003ctd\u003e50 x 50 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDebelina filtra\u003c\/td\u003e\n\u003ctd\u003e3 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVrsta\u003c\/td\u003e\n\u003ctd\u003eFilters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIzvedba\u003c\/td\u003e\n\u003ctd\u003ePass Filters\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSerija\u003c\/td\u003e\n\u003ctd\u003eBessel UBVRI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e","brand":"Baader","offers":[{"title":"Default Title","offer_id":57535367119221,"sku":"73921","price":257.37,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0694\/8166\/0719\/files\/Baader-Filters-UBVRI-Bessel-U-50x50mm_cd46ab36-e0d1-41a9-a0aa-22696191e793.jpg?v=1788092554","url":"https:\/\/starfy.si\/products\/baader-ubvri-bessel-u-fotometricni-filter-50-x-50-mm-73921","provider":"Starfy.si","version":"1.0","type":"link"}
