Hnab2 kho qhov muag muaju

Muaju calcium Fluoride (CaF2 los yog Fluorite) yog pob tshab rau qhab txaus ntshai. Cov khoom muag pom siv nyob rau hauv lub qhov rais, lo ntsiab muag khiav dej num UV thiab IR spectrum qhab. Laser siv: Calcium Fluoride tseem siv raws li tus tswv tsev lattice rau laser muaju. Vim nws muaj pes tsawg leeg, CaF2 tau muaj ntau pab tau lawm lub neej dua ntaub ntawv feem ntau thaum nyob ib puas ncig fluorine.

Nta:

  • Siab broadband transmittance los ntawm kev nqus UV mus IR (130 nm txog 8 microns)

  • Tsis tshua muaj refractive index (nd = 1.43384)

  • Tsis tshua muaj dispersion (vd = 95.23)

  • Ntau laser xauv nyob optics Excimer Laser (157nm, 193nm, 248 nm)

Kev siv:

  • IR optics

  • Optics rau astronomical instrumentation

  • Yeeb yaj tsom optics

  • Spectroscopy optics

  • UV optics

  • Laser qhov rais

  • Excimer Laser Optics

  • Microlithography Optics

Specification

Fluoride calcium uas siv lead ua muaj ntau kis los ntawm cov UV rau IR (0.13-11µm). Sythetic CaF2 yog siv los ua kom kis tau tus mob sib sib zog nqus UV thiab ua rau kom tus puas Harbor. Fluoride calcium (CaF2) yog muaj doped muaj Europium ua ib gamma-duab tshav scintillator.
