Quartz Blanks

Quartz Blanks constitute the initial, but very important step of the production process for FCPs. MORION command the entire spectrum of processing steps from precision X-ray orientation and doubly rotated cuts to high-quality surface lapping an polishing.

As we use our own quartz blanks in-house for our own line of oscillators, filters and crystals, the persistent continuous quality of our blanks and lenses is of paramount importance not only for our customers, but also for ourselves. From our design and manufacturing experience for oscillators and filters, we also know exactly, which blanks are required for your specific applications.

During recent years MORION has been putting a lot of efforts into quartz blanks production technology improvements in order to be able to produce high quality top level quartz blanks with tight angle accuracy and mainly for doubly rotated cuts. New equipment like EFG X-ray machines and our own technological know-how allowed us to become a supplier to the world major manufacturers of precision quartz FCPs.

In particular we manufacture quartz blanks which meet the following range of specifications:

Material	Cultured quartz Swept or non-swept
Q-Factor	(1.8 ... 2.8)x106
Cut	SC, IT, FC, AT, BT and as specified
Orientation Accuracy: AT-cut BT-cut SC-cut	up to xx'=±5', zz'=±15" xx'=±5', zz'=±30" xx'=±1', zz'=±10"
Shapes	Round with flat, rectangular, plano-plano, plano-convex, bi-convex, with or without bevel
Frequencies:	.
Plano-plano	f<45 MHz, AT- cut fundamental f<72 MHz, BT-cut fundamental
Plano-convex	1 MHz < f < 7 MHz, fundamental, <16 MHz, 3rd overtone, <30 MHz, 5th overtone
Bi-convex	0,8 MHz < f < 2 MHz
