Unique feature for PanelUnique feature for Panel
applicationapplication
Radioresistance is twice of glass
which can effectively reduce the
harm of electromagnetic wave
High transmittance leads to low
diffusion which can prevent light
scattering and eye fatique
High intensity and wear-
resistance-Mohs scale is 9 just
next to diamond
High sensitivity & easily
assemble
