Spherical Concave Optical Mirrors nrog Hlau Txheej
Paralight Optics muab cov iav concave nrog ob qho tib si hlau thiab dielectric reflective txheej.Cov iav hlau muaj qhov cuam tshuam zoo heev (90-95%) dhau qhov dav ntawm qhov dav, thaum cov iav dielectric-coated muab qhov kev xav tau ntau dua (> 99.5%) tab sis dhau qhov me me wavelength ntau.
Cov iav iav yog muaj nyob rau hauv focal ntev ntawm 9.5 - 1000 hli, thaum dielectric concave iav muaj nrog focal ntev ntawm 12 - 1000 hli.Broadband hlau-coated concave iav yog muaj rau siv nrog lub teeb nyob rau hauv lub UV, VIS, thiab IR spectral cheeb tsam.Yog xav paub ntxiv txog cov coatings, thov xyuas cov duab hauv qab no rau koj cov ntaub ntawv siv.
