Single crystal quartz wafers by Vritra Technologies

High purity single crystal Quartz wafers


We offer high purity SAW and optical grade single crystal quartz wafers grown by hyrothermal method. Wafers are available in various orientations namely: X-Cut, Y-Cut, Z-Cut, AT-Cut and ST-Cut. Quartz wafer have excellent thermal conductivity, high working temperature, high optical transmittance and unique piezoelectric properties. Due to these properties, Quartz wafers find numerous applications in semiconductor industry, optical lens manufacturing, in microwave filters, optical fiber etc. Wafers are available in 2 Inch, 3 Inch, 4 Inch and 6 Inch diameter with single side or double side polishing (optically transprent). Specifications can be customized as per your requirement.
