Muraayadaha Achromatic ee Dahaarka leh ee Broadband AR
Sharaxaada Alaabta
Muraayadaha achromatic lenses waa noocyada lenses kuwaas oo loogu talagalay in ay yareeyaan aberration chromatic, taas oo ah dhibaatada caadiga ah ee indhaha oo sababa in midabadu si ka duwan u muuqdaan marka la dhex marayo muraayada. Muraayadahani waxay isticmaalaan isku-darka laba ama in ka badan oo qalab indho-indhayn ah oo leh tusiyo-celin kala duwan si ay diiradda u saaraan hirarka dhaadheer ee iftiinka isla bartaas, taas oo keenta diiradda fiiqan ee iftiinka cad. Lenses Achromatic waxaa si weyn loogu isticmaalaa codsiyo kala duwan sida sawir qaadis, mikroskoobyo, telescopes, iyo muraayadaha indhaha. Waxay caawiyaan si ay u wanaajiyaan tayada sawirka iyaga oo yareynaya geesaha midabka oo soo saara sawirro fiiqan oo sax ah. Waxa kale oo si caadi ah loogu isticmaalaa nidaamyada laysarka iyo aaladaha indhaha ee u baahan saxnaanta sare iyo caddaynta sida qalabka caafimaadka, spectrometers, iyo qalabka xiddigiska.
Broadband AR Dahaarka Achromatic Lenses waa muraayadaha indhaha oo bixiya awoodo sawir oo tayo sare leh oo badan oo kala duwan oo ah hirarka iftiinka. Muraayadahani waxay ku habboon yihiin codsiyo kala duwan oo ay ku jiraan cilmi-baaris cilmiyeed, sawir-qaadista caafimaadka iyo tignoolajiyada hawada sare.
Haddaba waa maxay dhab ahaan muraayadda AR ee dahaarka leh ee achromatic? Marka la soo koobo, waxaa loogu talagalay in lagu xalliyo dhibaatooyinka aberration chromatic iyo luminta iftiinka ee dhici kara marka iftiinku ka soo baxo muraayadaha dhaqanka. Aberration Chromatic waa dhalanrog muuqaal ah oo ay keento lens-ku awood la'aanta in uu diiradda saaro dhammaan midabada iftiinka isla bartaas. Muraayadaha achromatic waxay xalliyaan dhibaatadan iyagoo isticmaalaya laba nooc oo kala duwan oo galaas ah (sida caadiga ah muraayadda taajka ah iyo muraayadda dhagaxa ah) si ay u abuuraan hal muraayad oo diiradda saari kara dhammaan midabada iftiinka isla goobta, taasoo keentay sawir cad oo fiiqan.
Laakiin muraayadaha achromatic waxay inta badan la kulmaan luminta iftiinka sababtoo ah milicsiga dusha muraayadda. Tani waa halka dahaarka AR ee balaastikada ah ay ka soo galaan. AR (ka-hortagga milicsiga) dahaarka waa lakab khafiif ah oo walax ah oo lagu dhejiyay dusha muraayadda kaas oo ka caawiya yaraynta milicsiga iyo kordhinta qadarka iftiinka lagu kala qaado muraayadda. Dahaarrada Broadband AR waxay hagaajiyaan dahaarka caadiga ah ee AR iyagoo u oggolaanaya gudbinta iftiinka si ka sii ballaaran oo ballaaran oo dhererkiisu yahay.
Si wada jir ah, muraayadda achromatic iyo daahan ballaaran ee AR waxay bixiyaan nidaam indho-indheyn oo awood leh oo kor u qaadi kara waxqabadka codsiyo kala duwan. Waxaa loo isticmaalaa wax kasta laga bilaabo spectrometers ilaa telescopes iyo xitaa nidaamyada laser. Sababtoo ah awoodda ay u leeyihiin in ay gudbiyaan boqolkiiba sare ee iftiinka guud ahaan spectrum ballaaran, muraayadahani waxay bixiyaan sawir fiiqan, tayada sare leh ee deegaan iyo codsiyo kala duwan.
Muraayadaha achromatic-ka ee dahaarka leh ee Broadband AR waa nidaam indho-indheyn awood leh oo bixin kara sawir-qaadis tayo sare leh oo ku saabsan hirarka dhaadheer ee iftiinka. Maaddaama ay tignoolajiyadu sii socoto inay horumarto, muraayadahani waxay shaki la'aan ka ciyaari doonaan door muhiim ah oo sii kordheysa ee cilmi-baarista sayniska, sawirka caafimaadka, iyo codsiyo kale oo aan la tirin karin.
