The newly upgraded finesse pure CEP (patented technology) brings together the ultra-low noise and high pointing stability of the finesse pure together with CEPLoQ™ technology. The ability to receive a signal from the f-to-2f interferometer removes the cost and complexity associated with the use of an AOM and offers a faster and deeper modulation capability to provide a more stable CEP stabilisation lock. The latest members of the finesse family will continue to drive innovative research through world-leading specifications, combined with dependable reliability.
