LGS-2 Tijaabada CCD Spectrometer
Sharaxaada
LGS-2 Spectrometer-ka Tijaabada ee CCD waa qalab cabbirid ujeedo guud.Waxay u isticmaashaa CCD sidii unug qaataha si ay si wayn u kordhiso arjigeeda kala duwan, oo awood u leh helida waqtiga-dhabta ah iyo soo bandhigida 3-cabbir ah.Waa qalab ku habboon in lagu daraaseeyo spectra ee ilaha iftiinka ama lagu cabbiro shaybaarrada indhaha.
Waxay ka kooban tahay monochromator grating, unugga CCD, nidaamka iskaanka, cod-weyneeye elektaroonig ah, unugga A/D iyo PC.Qalabkani waxa uu isku xidhaa optics, mishiinada saxda ah, elegtarooniga ah, iyo sayniska kombiyuutarka.Cunsurka indhaha ayaa qaata qaabka CT-ga ee hoos lagu muujiyey.
Qalafsanaanta monochromator-ka ayaa wanaagsan, dariiqa iftiinka ayaa ah mid aad u xasilloon.Albaabka laga soo galo iyo ka bixista labaduba waa toosan oo balac si joogto ah loogu hagaajin karo min 0 ilaa 2 mm.Dhuxulku wuxuu dhex maraa slit Slit1(S1waxa uu saaran yahay dayuuradda xudunta u ah muraayadda is-burburinta milicsiga), ka dibna waxaa ka tarjumaysa muraayadda M2.Iftiinka isbar-bar yaacaya wuxuu u toogtaa shabaqyada G. Mirror M3waxay samaysaa sawirka iftiinka kala duwanaanshiyaha wuxuu ka yimaadaa shabaqyada S2ama S3( muraayadda weecinta M4wuxuu ururin karaa jeexa ka bixista, S2ama S3).Qalabku wuxuu isticmaalaa habka sinaha si uu u gaadho sawirka hirarka dhererka.
Deegaanka la doorbido ee qalabku waa xaaladaha shaybaadhka caadiga ah.Aaggu waa inuu ahaadaa mid nadiif ah oo leh heerkul deggan iyo qoyaan.Qalabku waa inuu ku yaal meel siman oo fidsan (taageerada ugu yaraan 100Kg) oo leh meel bannaan oo ku wareegsan hawo-qaadista iyo isku xirka koronto ee lagama maarmaanka ah.
