| It's userd in DSCs |
|
Quartz crystal devices are also used in DSCs, along with quartz crystal units in optical devices.
They play a vital role in CCDs, where they compensate the optical "bleeding" peculiar to CCDs. They are an essential component of SLR and compact cameras. |

 |
| Used in a variety of electronic components |
|
Quartz crystal devices include quartz crystal units, quartz crystal oscillators and quartz crystal filters. Quarts crystal devices are also used in a range of sensors.
Quartz crystal units consist of a wafer of quartz to which are attached metallic electrodes. They are enclosed in a sealed package and oscillate when connected to an oscillation circuit. |

|
| Quartz crystal oscillators combine semiconductors and quartz crystal units, and emit an oscillation signal when the power is switched on. There are many different kinds of oscillator, some with highly precise temperature compensation circuits, others enclosed in constant temperature ovens. |

|
|
| There are two basic types of quartz crystal filter: monolithic crystal filters and surface acoustic wave (SAW) filters. These devices allow the selection of the desired signal and help to achieve interference-free communication. |
