Optical frequency references
Accurate and stable optical frequencies are a cornerstone of quantum technology and metrology. Our ultrastable LFR Series optical frequency references provide excellent absolute accuracy and stability, and are ideal tool for a variety of applications, such as optical frequency measurements and calibration, quantum communication, interferometry and ranging. With a highly compact form factor and lightweight design, they are suitable for spatially constrained applications, and are available at several wavelengths.
