QUZS UV Grade Quartz Substrate
B 20-10 Scratch and Dig (Double Side Typ.)
< Lambda/10 @ 632.8nm over 1-inch area on-jig tested
B-Grade Quartz substrates, Quartz plates, slides, wafers and Quartz windows are used for imaging / coating purpose and material processing.

Features of B-Grade Quartz Glass Substrates include:
Purity: High purity levels eliminates contamination in the quartz substrates.
Chemical resistance: Excellent thermal shock resistance and quartz glass is chemically inert to most elements and compounds including virtually all acids.
Heat resistance: High dimensional stability of the quartz glass over a wide temperature range with extremely low coefficient of thermal expansion.
Transparency: Quartz glass allow a high transmission over a wide range of wavelengths from UV to IR.
