CaF2 (calcium fluoride) qhia tau zoo kho qhov muag thiab thermo-mechanical zog. Nws yog dav siv raws li qhov rais optical, lo ntsiab muag, thiab prisms nyob rau hauv 0.13μm ~ 10μm, siv rau uv thiab ir spectral siab kis daim ntaub ntawv zoo li rau cov kev siv laser. Rau nws cov isotropy kho qhov muag, koj lub laser fais fab tuag puas tsuaj, tsis tshua txaus siab, thiab nqhis dej Performance index, CaF2 (calcium fluoride) tau pom muaj qhov tshwj xeeb zoo hauv laser thiab vu laser optics, uas yuav siv tsis tau los tiv thaiv txheej txheem rau cov ntawv tsis-laser .
CaF2 (calcium fluoride) Cheebtsam yog cov nyuab nyuab rau kev tsim tawm hauv cov khoom muaj tiag. Cov khoom siv nws tus kheej yog mos muag thiab yooj yim tawm ntawm qhov cim tseg thiab cov khawb ntawm qhov chaw ntawm qhov chaw. Honour optics kuj muaj kev pab polishing. Ntawm qhov yawm optics, peb qhov kev txawj ntse hauv kev to taub cov qauv siv lead ua rau peb ua kom zoo dua thiab pab kom peb muaj kev zoo heev, peb tus txheej txheem zoo yog 60/40, siab tshaj 10/5. Honour optics yog cov kev xa cov laser high performance lias CaF2 optics thiab lub voj, uv thiab qib qib ntawm CaF2 optics, txais tos rau kev sib tham tswv yim /kev sib tw /kheej /cylindrical CaF2 optics muag nqi.
CaF2 (calcium fluoride) yog optically isotropic, non-hygroscopic thiab insoluble feem ntau cov acids thiab alkali, yog li ntawd, qhov chaw phom sij yog suab tsis degraded nyob rau hauv tej yam kev mob atmospheric. Ib lub tshuab ua zog siab ua kom nws muaj txiaj ntsig rau kev siv tshuab muaj zog. CaF2 (calcium fluoride) kuj tseem ceeb heev rau thermal shock.
Degradation vim dej noo hauv qhov chaw yog tsawg, thiab qhov rais ci ntawm lub qhov rais CaF2 tej zaum yuav tau tuaj yeem tiv thaiv tau ntau xyoo 'raug rau cov neeg mob tsis zoo rau lub cev. Ntxiv rau hauv, CaF2 tus nplais yog non-axial, thiaj tsis muaj kev xav txog txoj kev xav axial.
CaF2 (calcium fluoride) tawm tsam cua ntsig txog 600 ° c, qhov twg nws pib muag muag. Qhov ntsuas kub siab tshaj plaws yog siv li ntawm 800c thaum tsis muaj dej noo. Irradiation ntawm CaF2 cov qhov rais ua rau qee lub poob qis hauv cov kev ntsuas uv.
Zoo siab Suav CaF2 optics siv nyob rau hauv cov uv, vis, nir thiab /los yog cheeb tsam ncig thaj chaw. Nws yog ob zaug li nyuaj li baf2. CaF2 tsis tshua muaj mob thermal poob siab tshaj li baf2. CaF2 tsis degrade vim yog ya raws hauv ambient atmospheric. CaF2 tsis tshua kim tshaj baf2. CaF2 yog qhov yooj yim tshaj plaws nyob hauv qhov loj loj tshaj li baf2. CaF2 yog diamond turnable.
Cov khoom tsim: Cov xim kheej kheej kheej thiab cylindrical, lo ntsiab muag aspheric, qhov rais, optical beamsplitters, optical lim, wedges, prisms.
Qhov xaus: Cov zom ntawm 20-10 cov khawb khawb yog feem ntau teev rau kev siv hauv cov ntaub ntawv thiab cov ntawv pom. 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: Hauv cov cheeb tsam uv thiab pom thaj chaw spectral, daim duab kos yog qhov ntev ntawm 1/10 nthwv dej rau 1/4 yoj @ 0.6328μm. Hauv cov ntaiv, feem ntau yuav tsum tau daim duab yog li ntawm 1/4 yoj mus rau 2 lub vuag @ 0.6328 μm thiab raug teev nyob rau ntawm qhov kev ua haujlwm rau kev ua haujlwm.
Ar txheej kev xaiv: Muaj cov coatings rau customized loj loj thiab tshwj xeeb zoo CaF2 optics xws li bbar rau 0.8 rau 2.5μm, 3 mus rau 5μm los yog thaj tsam ntawm 1 mus rau 5μm spectral
