CaF2 Windows-light Transmission Performance From Ultraviolet 135nm ~ 9um

Nrog rau kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis, daim ntawv thov kev cia siab yog ntau dua thiab dav. Calcium fluoride muaj kev xa tawm siab nyob rau hauv qhov dav wavelength ntau yam (135nm txog 9.4μm), thiab yog lub qhov rais zoo tagnrho rau excimer lasers nrog luv wavelengths heev. Cov siv lead ua muaj qhov ntsuas siab heev ntawm refraction (1.40), yog li tsis tas yuav tsum muaj AR txheej. Calcium fluoride yog me ntsis soluble hauv dej. Nws muaj kev xa tawm siab los ntawm thaj av ultraviolet mus rau thaj tsam deb infrared, thiab haum rau excimer lasers. Nws tuaj yeem ua tiav yam tsis muaj txheej txheej lossis txheej txheej.Calcium Fluoride (CaF2) Qhov rai yog lub dav hlau sib txuas, feem ntau yog siv los ua lub qhov rais tiv thaiv hluav taws xob sensors lossis cov khoom siv hluav taws xob ntawm cov khoom siv sab nraud. Thaum xaiv ib lub qhov rais, yuav tsum tau them nyiaj mloog mus rau lub qhov rais cov khoom, transmittance, kis band, nto zoo, smoothness, parallelism thiab lwm yam tsis.

Lub qhov rais IR-UV yog lub qhov rais tsim los siv nyob rau hauv infrared los yog ultraviolet spectrum. Lub qhov rais yog tsim los tiv thaiv saturation los yog photodamage ntawm hluav taws xob sensors, detectors, los yog lwm yam rhiab kho qhov muag Cheebtsam. Cov khoom siv calcium fluoride muaj qhov sib kis dav dav (180nm-8.0μm). Nws muaj cov yam ntxwv ntawm kev puas tsuaj loj, tsis muaj fluorescence, siab uniformity, thiab lwm yam., nws lub cev muaj zog kuj yog mos, thiab nws nto yog ib qho yooj yim mus khawb. Nws yog feem ntau siv nyob rau hauv collimation ntawm lasers, thiab feem ntau yog siv raws li lub substrate ntawm ntau yam optical Cheebtsam, xws li lo ntsiab muag, qhov rais thiab lwm yam.
