Since starting production of synthetic quartz crystal in 1977, TEW continued to improve the quality and purity of our crystal. In 1994, we succeeded to develop a high-pressure autoclave (platinum autoclave) for mass production of synthetic quartz crystals with our own technology. Those technology enable us to mass product of high-quality synthetic quartz crystal with few defects. These high-quality synthetic quartz crystal are used as a raw material for various crystal product. |

TEW's crystal units are designed to be applicable for the requirement of high precision specification such as mobile communication or satellite communication. TEW's world top class ultra-thin and ultra-miniature crystal are available with high reliability of Seam sealed type and Au-Sn type. |
 |
TEW's crystal oscillators are used in electronic and electronic communication equipment, as the generator of a control signal for stable frequency and time. In particular, the application for the terminal of satellite-mobile and for base station has been rapidly expanded. TEW is supplying various crystal oscillators using highly reliable crystal units, circuit engineering, superior temperature compensation method and measuring method which is fostered by our long experience and activity. |
 |
TEW's crystal filters are widely used in communication systems and are offered with a center frequency ranging from 10.7MHz to 200MHz. TEW's thin-wafer technology has made it possible to make high reliable filters in various application. |
 |
TEW's optical Components are the products utilizing the optical property (double reflection) of quartz crystal. TEW is producing high grade optical components by using selected defect-free grade synthetic quartz crystals. |
