High Precision Square Thin Wall Quartz Glass Window

Product Description

Quartz Fused silica Plates are applied to isolate different physical environments meanwhile allowing light to drill through. When selecting windows, you should consider these factors,

materials, transmission, scattering, wavefront distortion, parallelism and resistance to certain

environment. ZCQ offers a wide range of different materials and different degree of precision

windows. Materials are UV Fused Silica, BK7, B270, CaF2, MgF2, etc.
