Round thick quartz plate

quartz plate used mainly for hearing control

far infrared control the manufacture.

we can make transparent\translucent\opaque square and circular plates .
 Quartz plates can be used for window material ,mask substrate or
heat insulation.We can make square and circular plates.
, all for a reasonable cost, these fwindows are ideal.
When the broadest transmission spectrum is required with high durability,  a reasonable cost, these windows are ideal. Fused Silica is physically robust and resists chipping and scratches,coefficient of thermal expansion is quite low, so these windows maybe subjected to higher levels of thermal shock than glass or sapphire can withstand.
