Chalcogenide Iav Lens rau Infrared Daim Ntawv Thov
Chalcogenide Iav Lens rau Infrared Daim Ntawv Thov
Cov ntaub ntawv khoom:
Lub iav Chalcogenide yog lub iav kho qhov muag ua los ntawm cov iav chalcogenide. Lub iav Chalcogenide tsis yog ib qho tab sis yog cov khoom siv amorphous zoo li iav uas xa mus rau hauv infrared band. Lawv muaj kev xa mus zoo (> 60%) hauv qhov ntau ntawm 2-12 micron, qis index of refraction (2.4-2.8@11micron), qis thermal hloov pauv hauv refractive index thiab qis dispersion. Lawv muaj cov khoom siv kho tshuab thiab kho qhov muag zoo ib yam li germanium, uas ua rau lawv zoo rau kev siv IR, tshwj xeeb tshaj yog hauv kev kho xim nrog germanium lens hauv lub cev kho qhov muag.
Tsis zoo li germanium, uas yuav tsum tau khawb thiab muaj tsawg, cov iav chalcogenide yog cov khoom siv hluavtaws thiab lawv cov nqi ruaj khov dua. Cov iav Chalcogenide muaj qhov kub yaj qis (200-400 ℃) piv rau lwm cov ntaub ntawv infrared, lawv tuaj yeem pwm rau hauv lub lens aspheric nrog tus nqi qis rau kev tsim khoom ntau ("Moulded IR-Molded Chalcogenide Iav Lens"). Vim ob qho laj thawj no, lub iav chalcogenide yuav ua lub luag haujlwm tseem ceeb dua hauv cov ntawv thov infrared.
Cov iav chalcogenide uas muaj qhov ntev ntawm lub teeb infrared tuaj yeem tsim tau ntau yam duab ntawm lub lens iav chalcogenide nrog rau cov nto dav hlau, concave, convex, aspheric thiab diffractive. Cov iav chalcogenide nrov tshaj plaws rau cov kab ke ua haujlwm hauv thaj tsam spectral 3-5 lossis 8-12µm, nrog rau cov txheej tiv thaiv kev cuam tshuam (AR txheej), qhov nruab nrab ntawm kev sib kis tuaj yeem nce mus txog 97.5-98.5% nyob ntawm qhov bandwidth ntawm cov txheej. Peb kuj tuaj yeem siv cov txheej txheem carbon zoo li pob zeb diamond (DLC txheej) lossis cov txheej txheem ruaj khov (HD txheej) rau ntawm qhov chaw ntawm lub lens kom muab kev tiv thaiv ntxiv tiv thaiv kev khawb thiab kev cuam tshuam.
Cov iav infrared wavelength tsim cov iav zoo uas muaj cov iav spherical thiab aspheric chalcogenide. Lawv tuaj yeem tsom lossis faib cov teeb ci ntsa iab los ua kom tau raws li qhov xav tau ntawm lub tshuab infrared. Daim ntawv thov tuaj yeem yog thermal imaging, thermograph, beam collimating, spectrum analysis thiab lwm yam.
