Saxnaanta Aplanatic
Achromatic Doublets

Muraayada achromatic, oo sidoo kale loo yaqaano achromat, ayaa caadi ahaan ka kooban 2 qaybood oo indho-indheyn ah oo la isku daray, sida caadiga ah curiye hoose oo togan (inta badan muraayadda muraayadda biconvex) iyo curiye index sare ah (sida muraayadda dhagaxa ah).Farqiga u dhexeeya tusmooyinka refractive dartiis, kala firidhsanaanta labada walxood qayb ahaan way isu magdhabaan midba midka kale, aberration chromatic marka la eego laba hirarka hirarka la doortay ayaa la saxay.Waxaa loo hagaajiyay si loo saxo labada dhidibka ku wareegsan iyo aberrations chromatic.Muraayada Achromatic waxay bixin doontaa cabbir yar iyo tayada muuqaal ka sarreeya muraayadda keliga ah ee la barbar dhigi karo oo leh isla dhererka focal.Tani waxay ka dhigaysaa inay ku habboon yihiin sawir-qaadista iyo codsiyada diiradda saaraya ballaadhan.Achromats waxaa loo qaabeeyey oo loo soo saaray si ay u qanciyaan dulqaadka ugu adag ee looga baahan yahay laser-ga wax qabad sarreeya ee maanta, elektro-optical iyo hababka sawir-qaadista.

Paralight Optics waxay bixisaa noocyo kala duwan oo ah achromatic optics oo leh cabbirada macaamiisha-qeexay, dhererka foorarka, alaabta substrate, alaabta sibidhka, iyo dahaarka ayaa si gaar ah loo sameeyay.Muraayadaha achromatic lensesyadayadu waxay daboolaan 240 - 410 nm, 400 - 700 nm, 650 - 1050 nm, 1050 - 1620 nm, 3 - 5 µm, iyo 8 - 12 µm dhererka hirarka.Waxa la heli karaa iyada oo aan la rakibin, lagu rakibay ama laba-labo is-bar-bardhigay.Marka laga hadlayo labanlaabyada achromatic-ka ee aan la rakibin & safka saddex-geesoodka ah, waxaan ku siin karnaa labanlaabyo achromatic (labadaba kuwa caadiga ah iyo kuwa saxda ah ee aplanatic), labajibbaaran achromatic cylindrical, lammaane labajibbaaran achromatic kuwaas oo loogu wanagsan yahay isku-xireyaasha xaddidan oo ku habboon habka gudbinta sawirka iyo nidaamka weyneynta, labajibbaaran achromatic-hawo leh kuwaas oo ku habboon codsiyada awoodda sare leh sababtoo ah heerka dhaawaca ka weyn kan achromat-ka sibidhka, iyo sidoo kale saddex-geesoodka achromatic kaas oo u oggolaanaya xakamaynta ugu sarreysa.

Paralight Optics 'Pralight Optics' Precision Aplanats (Aplanatic Achromatic Doublets) laguma saxo oo kaliya aberration spherical iyo midabka axial sida Standard Cemented Achromatic Doublets laakiin sidoo kale waxaa lagu saxay miyir-beelka.Isku-dhafkan wuxuu ka dhigayaa mid dabiici ah oo dabiici ah wuxuuna bixiyaa waxqabad muuqaal ah oo wanaagsan.Waxaa loo isticmaalaa sidii ujeeddooyin diiradda saaraya laysarka iyo habka elektro-optical & imaging.

Fiiro gaar ah: Si loo helo waxqabadka ugu fiican marka la isku darayo isha dhibicda, guud ahaan is dhexgalka hawada-ilaa galaas ee ugu horreeya ee leh radius weyn ee qalooca (dhinaca fidsan) waa in uu ka hor yimaadaa laydhka isku dhaca ee dib u jabay, si ka duwan marka diirada la saarayo laydhka isku dhafan, hawada-ilaa Isku-xidhka galaas ee leh dhexroorka gaaban ee qalooca (dhinaca aadka u qalloocan) waa in uu wajaho shilku laambad isku xidhan.
