BaF2 (Barium Fluoride) yog nyob rau qhov cubic siv lead ua los nrog cov dej noo tsis tshua txog, qhov nruab nrab ntawm 1280 ℃, uas tso cai rau BaF2 (Barium Fluoride) ua haujlwm hauv kev kub ntxhov, qhov ntsuas qis qis txawv me ntsis hauv kab dav dav wavelength. BaF2 (Barium Fluoride) yog siv cov khoom siv hauv UV thiab IR spectroscopy vim kev sib kis ntawm qhov ntev ntawm 150-200nm txog 11-11.5μm.
BaF2 (Barium Fluoride) siv tau los ua qhov muag zoo li qhov rais thiab lo ntsiab muag. Nws yog siv nyob rau hauv cov qhov rais rau infrared spectroscopy, nyob rau hauv particular nyob rau hauv lub tshav pob ntawm cov roj roj tsom. Nws qhov kev xa tawm ntawm 200nm yog tus qis dua (0.60), tab sis nyob ntawm 500nm nws mus txog 0.96-0.97 thiab qis qis txij li 9μm, ces nws pib poob tawm (0.85 rau 10μm thiab 0.42 rau 12μm). Lub ntsuas ua kom qis yog txog 1.46 ntawm 700nm rau 5μm. Honour Optics yog lub siab hloov UV thiab cov tub lag luam BaF2 optics tub lag luam, nqus loj BaF2 optics, txais tos rau cov lag luam Infrared thiab Broadband BaF2 optics.
BaF2 (Barium Fluoride) yog ib qho muag heev tiam sis nws muaj cov neeg kho mob thiab thermal shock, BaF2 (Barium Fluoride) tsis tshua yoog rau dej dua CaF2 (Calcium Fluoride), qhia tias dej tua tshwm li ntawm 500 ° C tiam sis tseem siv tau 800 ° C nyob rau hauv cov huab cua qhuav. Qhov siab tshaj plaws muaj qhov loj me me: Dia. 200 hli x Thickness 50 hli.
UV thiab IR qib BaF2 optics monocrystalline yog qhov zoo rau kev siv li UV qhov chaw uas muaj hluav taws xob ua haujlwm tsis txaus siab, piv txwv li, scintillation qib BaF2 feem ntau yog siv los ua ib qho scintillator rau gamma nrhiav. Nws yog tus ceev tshaj plaws scintillating crystals mus txog rau tam sim no thiab yog siv hauv High Energy Physics Experiments. Lwm yam kev siv nrog rau thermography thiab thermology khoom kho mob, laser thiab astronomy.
UV thiab IR qib BaF2 optics nrog kev xa xov ntau tshaj 90% ntawm 0.2-10μm wavelength qhab, thiab nce 0% ntawm li 0.18μm thiab 14μm. Nws yog ib hom phom khoom siv nrog HK82 hardness, thiab nrog cov dej tsis muaj zog, qhov no ua rau BaF2 optics yooj yim heev rau tau khawb thiab moistened; Txawm hais tias Barium Fluorides qis index ntawm refraction ntawm 1.48 muab siab kis, nws yuav siv tsis tau los tiv thaiv coatings, nws yog ib txwm zoo kom muaj kev tiv thaiv AR txheej rau siv nyob rau hauv 0.8-2.5μm, 3.0-5.0μm, 1.0-5.0 μm lossis lwm hom twg.
Customized plano /spherical /aspherical /cylindrical BaF2 optics txheem orientation yog < 111 > ;, thiab tsuas yog siv nyob rau hauv ze-infrared wavelength, thiab tseem yuav muab faib rau monocrystal thiab polycrystal. Tab sis nws yog ib qho nyuaj heev rau kev loj hlob monocrystal loj loj. BaF2 yog ntxiv muag thiab yog ib qhov nyuaj ua kom tau zoo dua ntu zoo dua CaF2. Yog li ob qho tib si cov ntaub ntawv nws tus kheej thiab polishing ua BaF2 optics kim heev.
Kev kho vaj tse /kheej kheej /kheej /cylindrical BaF2 optics feem ntau yog siv hauv VIS, NIR thiab /lossis MW spectral regions. Lub hardness ntawm BaF2 yog li ib nrab ntawm cov CaF2. BaF2 tseem raug ntxiv rau thermal poob dua CaF2. BaF2 yog me ntsis kim dua CaF2. Tsis yog raws li muaj nyob hauv ntau loj li CAF2. BaF2 yog diamond turnable.
Cov khoom tsim: Khais kheej kheej, Qhov muag lo ntsiab muag Aspheric, Qhov rais, Optical Beamsplitters, Optical Filters, Wedges, Prisms.
Qhov xaus: Cov kab ntawm 20-10-khawb cov kabmob feem ntau yog siv rau kev siv hauv UV thiab pom daim ntaub ntawv. Cov lus qhia tshwjxeeb rau qhov zoo hauv lub khov nabnpawb yog 40-20 khawb-khawb hauv 0.75 rau thaj tsam ntawm 3μm thiab 60-40 khawb-khawb rau thaj chaw 3-7μm.
Daim duab ntawm daim duab: Tus duab saum npoo ntawm 1/10 nthwv dej mus rau 1/2 yoj @ 0.6328 μm yog qhia txog feem ntau ntawm lo ntsiab muag rau ultraviolet thiab pom siv. Hauv daim duab infrared, feem ntau yuav tsum tau npoo ntawm qhov 1/2 yoj mus rau 2 lub vuag @ 0.6328 μm nyob ntawm qhov kev ua haujlwm rau kev ua haujlwm.
AR txheej kev xaiv: Feem ntau muaj coatings rau BaF2 muaj xws li BBAR rau 0.8 rau 2.5 μm, 3 mus rau 5μm los yog cheeb tsam ntawm 1 mus rau 5μm spectral.
