DFC PURACY
Difference frequency comb with sub-kHz linewidth and long-term stability
A difference frequency comb with spectral purity and absolute accuracy. This is DFC PURACY. One click is all it takes to get low phase noise, narrow linewidth, and rock-solid long-term stability. No juggling, no compromises. Just clean, absolute frequencies traceable to the SI second and a system that quietly takes care of itself in the background.
Thanks to the automated simultaneous lock to optical and RF references, daily laser calibration becomes a thing of the past. You save time, gain confidence, and stay focused on what really matters. Whether you are upgrading from DFC CORE + or building something new, PURACY fits right in and elevates your setup with ease.
From precision spectroscopy to robust infrastructural comb systems and photonic microwave and THz generation, DFC PURACY opens the door to applications where spectral purity and absolute accuracy truly make a difference.

Your Benefits
Sub-kHz linewidths
Long-term stable frequency comb with low phase noise for narrow linewidths.
No PhD required: automated locking with one click
We offer world-record stability at the push of a button with automated simultaneous locking to optical and RF references and remote control via a single interface.
Cost-efficient upgrade to DFC CORE +
Get the full solution. Enable new possibilities.
Absolute frequencies traceable back to the SI second
DFC PURACY can be referenced to a GPS-disciplined RF source that is ultimately linked to atomic clock standards, traceable to the SI second.
Save time on daily laser calibration
The combination of low phase noise and absolute accuracy equips your locked lasers with narrow linewidth and eliminates the need for daily manual calibration.
