Galasi la Chalcogenide lopangidwa ndi infrared
Galasi la Chalcogenide lopangidwa ndi infrared
Zambiri za malonda:
Magalasi achikhalidwe a infrared amaphwanyidwa, kupukutidwa kapena kusinthidwa diamondi kuti apange pamwamba pake, mwa kuyankhula kwina: kudzera mu "kupanga kozizira". Ngakhale magalasi a infrared amathanso kupangidwa kudzera mu "kupanga kutentha", apa tapanga magalasi a infrared opangidwa ndi galasi la chalcogenide. Kuumba magalasi ndikofunikira kwambiri popanga zinthu zambiri chifukwa mtengo wopangira pa lenzi iliyonse ukhoza kulamulidwa pang'ono kwambiri. Magalasi opangidwa ndi ulusi alinso ndi kusinthasintha kwabwino kwa zinthu popanga zinthu zambiri, zomwe zimatsimikizira kudalirika kwa machitidwe a infrared.
Galasi la Chalcogenide si limodzi koma ndi mndandanda wa zinthu zopanda mawonekedwe ofanana ndi galasi zomwe zimafalikira mu gulu la infrared. Titha kusankha zinthu zagalasi la chalcogendie zokha mu infrared lens chifukwa cha malo awo otsika osungunuka poyerekeza ndi zinthu zina za infrared.
Magalasi a Chalcogenide ali ndi mphamvu yabwino yotumizira (>60%) pakati pa 2-12 micron, index yotsika ya refraction (2.4-2.8@11micron), kusintha kochepa kwa kutentha mu refractive index komanso kufalikira kochepa. Ali ndi mphamvu zofanana ndi za makina ndi kuwala monga germanium, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito mu infrared, makamaka pokonza mitundu ndi germanium lens mu optical system.
Mosiyana ndi germanium yomwe imafunika kukumba ndipo ili ndi zochepa, magalasi a chalcogenide ndi opanga. Mitengo yawo ndi yokhazikika komanso yovomerezeka. Magalasi opangidwa ndi galasi la chalcogenide akhoza kukhala abwino m'malo mwa magalasi a germanium omwe angathandize kwambiri pamakina atsopano a infrared.
Magalasi a infrared a Wavelength amatha kupereka magalasi a infrared a chalcogenide okhala ndi malo a aspheric komanso diffractive. Magalasi a Chalcogenide ndi otchuka kwambiri pamakina omwe amagwira ntchito mu gulu la 3-5 mircron kapena 8-12 micron infrared, ndipo avareji ya transmission ndi 97.5% yokhala ndi zophimba zotsutsana ndi kuwala (AR). Zophimba za kaboni zofanana ndi diamondi (DLC) kapena zophimba zokhazikika (HD) zitha kugwiritsidwanso ntchito pa magalasi a infrared a chalcogenide kuti apereke chitetezo chowonjezera ku zokwawa ndi kugunda.
Mafotokozedwe:
Mafunde a infrared amapereka lenzi ya infrared yagalasi ya chalcogenide yokhala ndi mainchesi 1-25. Chophimba chathu chokhazikika cha AR ndi DLC ndi choyenera kwambiri pa band ya 3-5 kapena 8-12 micron. Kutalika kwa ma lenzi athu kungawongoleredwe mpaka +/-1%, kusakhazikika kwa pamwamba kosakwana 0.5 micron, ndi kugawa kwa lenzi kosakwana mphindi imodzi ya arc.
| Zinthu Zofunika | Galasi la Chalcogenide |
| M'mimba mwake | 1mm-25mm |
| Mawonekedwe | Aspheric/Diffractive |
| Kutalika kwa focal | <+/-1% |
| Kuchepetsa mphamvu | <1 mphindi ya arc |
| Kusakhazikika kwa pamwamba | < 0.5 maikuloni |
| Chitseko Choyera | >90% |
| Kuphimba | AR, DLC kapena HD |
Ndemanga:
1. Zophimba za DLC/AR kapena HD/AR zimapezeka mukapempha.
2. Kusintha kwa zinthuzi kulipo kuti zigwirizane ndi zosowa zanu zaukadaulo. Tiuzeni zomwe mukufuna.
MAGULU A ZOPANGIDWA
Kutalika kwa mafunde kwakhala kukuyang'ana kwambiri pakupereka zinthu zowunikira zolondola kwambiri kwa zaka 20.
