Quartz Wafers

Product Description:

Besides the applications as waveplates for optical polarization transformation, Quartz crystal is widely used in frequency control applications due to its fundamental properties including high purity, high Q, low thermal expansion, excellent stability, unique electrical characteristic and low cost. Especially, a device employing quartz as a resonator has risen rapidly due to the development in the mobile telecommunications fields. Precision Micro-Optics offers high quality quartz wafers in a very competitive pricing. The wafers are free from chips and scratches. The growth and lapping procedures assure the high quality and the high yield. A variety of wafers are available with different cutting orientations, thickness as thin as 0.2mm and diameter up to 6 inches. Custom requirements are welcome upon request.
