Shaandheeyayaasha Tignoolajiyada Sare iyo Polarizers/Waveplates
Filterku waa nooc gaar ah oo daaqad fidsan ah kaas oo, marka la dhigo dariiqa iftiinka, si door ah u gudbiya ama diidaya tiro gaar ah oo dhererka hirarka (=midab).
Astaamaha indhaha ee shaandhada waxa lagu sifeeyaa jawaab celintiisa soo noqnoqota, kaas oo qeexaya sida shilka iftiinka iftiinka uu wax uga beddelo shaandhada, waxaana lagu muujin karaa garaaf ahaan khariidadiisa gudbinta ee gaarka ah.
Noocyada kala duwan ee filtarrada la beddeli karo waxaa ka mid ah:
Shaandhooyinka nuugista ayaa ah filtarrada ugu fudud kaas oo ka kooban aasaasiga ah ee substrate-ka ama dahaarka gaarka ah ee lagu dabaqay uu nuugo ama gebi ahaanba xannibo hirarka dhererka aan loo baahnayn.
Shaandhooyin badan oo kakan ayaa ku dhaca qaybta filtarrada dichroic, haddii kale loo yaqaan filtarrada "filan" ama "filim khafiif ah".Shaandhooyinka Dichroic waxay isticmaalaan mabda'a faragelinta: lakabadoodu waxay sameeyaan taxane isdabajoog ah oo milicsi iyo/ama nuugaya lakabyo, taas oo u oggolaanaysa habdhaqan aad u sax ah gudaha mawjada la rabo.Shaandhooyinka Dichroic ayaa si gaar ah faa'iido u leh shaqada saxda ah ee sayniska sababtoo ah mawjadaha saxda ah ee dhererkooda (kala duwanaanta midabada) ayaa si aad ah loo xakameyn karaa dhumucda iyo nidaamka daboolka.Dhanka kale, guud ahaan way ka qaalisan yihiin oo way ka jilicsan yihiin filtarrada nuugista.
Sifeeye Cufnaanta Dhexdhexaadka ah (ND): Noocan shaandhada aasaasiga ah waxaa loo isticmaalaa in lagu yareeyo shucaaca shilka iyada oo aan la beddelin qaybinteeda muuqaalka ah (sida dhalada filter Schott oo buuxa).
Shaandhooyinka Midabka (CF): filtarrada midabka ayaa nuugaya filtarrada ka samaysan muraayad midab leh oo nuuga iftiinka meelo kala duwan oo dherer ah ilaa heerar kala duwan oo u gudbiya iftiinka meelo kale ilaa xad weyn.Waxay yaraynaysaa ku wareejinta kulaylka iyada oo loo marayo nidaamka indhaha, si wax ku ool ah u nuugaya shucaaca infrared iyo kala daadinta tamarta la ururiyay ee hawada ku wareegsan.
Sidepass/Bandpass Filters (BP): Shaandhaynta bandpass indhaha waxa loo isticmaalaa in lagu kala doorto qayb ka mid ah spectrum iyadoo la diidayo dhammaan mowjadaha kale ee dhererka.Kala duwanaanshahan shaandhada dhexdiisa, filtarrada-dhaafka-dheer waxay kaliya u oggolaanayaan hirarka dhaadheer inay dhex maraan shaandhada, halka filtarrada gaaban ay oggolaadaan oo keliya hirarka dhererka yar inay gudbaan.Shaandhooyinka-dhaafka dheer iyo kuwa-gaaban ayaa faa'iido u leh go'doominta gobollada spectral.
Filter Dichroic (DF): Filter-ka dichroic waa shaandhooyin midab aad u sax ah oo loo isticmaalo in si door ah loogu gudbiyo midabyo yar oo iftiin ah iyada oo si wax ku ool ah uga tarjumaysa midabyo kale.
Shaandhooyinka Waxqabadka Sare: Waxaa ku jira baska dheer, baska gaaban, baasaaska, bandstop, baasas laba geesood ah, iyo sixitaanka midabka ee mawjadaha dhererka kala duwan ee codsiyada u baahan xasilloonida indhaha iyo adkeysiga gaarka ah.
