Time and Frequency

The purity of Sapphire

“The purest signal available on the commercial market”


To be the premier, sovereign provider of highest precision products and support services for timing, instrumentation & sensors.

Cryoclock develops ultra-high precision time and frequency solutions in the HF and X-band.

At the heart of our world-leading technology is an ultra-pure sapphire crystal, which can generate signals a thousand times more pure than any other commercial system currently available.


Precise control of the cryogenic temperature of the sapphire enables unparalleled short-term stability. Coupled with our expertise for ultra-low noise synthesis, the result is a “turn-key” system that generates any frequency ranging from HF to X-band – the ultimate in precise frequency reference.

pure -- stable -- Cryoclock
