MgF2 muaju kho qhov muag

Fluoride magnesium (MgF2) yog siv UV qhov rais, lo ntsiab muag thiab polarisers. Nws tseem pab tau rau hauv cov kis ntau rau tej kev siv IR spectroscopy. Qhov rai Fluoride (MgF2) magnesium muaj yav tom ntej broadband kis los ntawm qhov tob-UV rau lub mid-infrared. DUV kis tau tus mob yuav ua rau lawv zoo tagnrho rau siv thaum lub Hydrogen Lyman-alpha kab thiab kev UV kev tawg pab thiab receivers, raws li kev siv laser excimer. Qhov rais, lo ntsiab muag, thiab cov xwm uas ua los ntawm cov khoom no yuav siv tau nyob rau tag nrho khwv yees li ntawm wavelengths los 0.120 μm (xau ultraviolet) rau 8.0 μm (infrared). MgF2 yog tawv thiab cov ua haujlwm thiab polishes zoo, tiam sis nws yog birefringent me ntsis thiab yuav tsum tau muab txiav nrog lub optic axis lawv rau lub dav hlau ntawm lub qhov rais los lens, feem ntau, Magnesium Fluoride laser siv mis yuav mus oriented nyob rau optic axis kom tsis txhob muaj teebmeem birefringent. Muaj qabhau heev rau daim ntawv thov laser excimer.

Nta:

  1. Mob kis los ntawm 120nm los 7μm

  2. Rugged thiab check

  3. Tshuaj Etching tiv taus
