Hastings Cemented
Achromatic Triplets

Muraayadaha achromatic waa doorasho wanaagsan oo lagu dalbanayo xakamaynta aberration-ka ugu badan, maadaama ay bixiyaan wax qabad aad uga wanaagsan marka loo eego halbeegyada wareegsan. Labanlaabyada achromatic cemented ayaa ku filan codsiyada badankooda ee isku dhafka aan dhammaadka lahayn, iyo lammaane sibidh leh ayaa ku habboon isku-xidhayaasha xaddidan. Si kastaba ha ahaatee, saddex-geesoodka ah ee Achromatic waxay bixiyaan waxqabad ka fiican marka loo eego labajibbaarka achromatic, xaqiiqda dhabta ah ee achromatic triplet waa muraayadda ugu fudud ee saxaysa dhammaan cilladaha asaasiga ah ee chromatic waxayna bixisaa waxqabadka dhidibka iyo dhidibka ka baxsan.

Saddex-geesoodka achromatic wuxuu ka kooban yahay curiye dhexe oo taaj hoose ah oo sibidheeyay inta u dhaxaysa laba walxood oo dhagax sare leh oo isku mid ah. Saddexdan saddex-geesoodka ah waxay awoodaan inay saxaan axial iyo aberration chromatic labadaba, naqshadooda summaysan waxay bixisaa waxqabad la xoojiyay marka loo eego labanlaabyada sibidhka.

Hastings achromatic triplets waxaa loogu talagalay inay bixiyaan saamiga isku-xidhan ee aan dhammaadka lahayn waxayna faa'iido u leeyihiin diiradda saarista alwaaxyada isku-dhafka ah iyo weyneynta. Marka la barbardhigo, Steinheil achromatic triplets waxaa loogu talagalay inay bixiyaan saamiga isku xidhka kooban iyo 1:1 sawir. Paralight Optics waxay bixisaa labadaba Steinheil iyo Hastings achromatic triplets oo leh dahaarka ka-hortagga ee cabbirka dhererka dhererka 400-700 nm, fadlan ka eeg garaafka soo socda tixraacyadaada.
