Menlo Systems' SMART-COMB is a full optical metrology system in a revolutionary compact package measuring 3U (5.25") x 19". This is the first model in a new era of optical frequency combs. SMART-COMB is a unique system where the user simply plugs in the optical fiber of the laser being measured or stabilized, while SMART-COMB does the rest. The module features fully automated locking electronics, fully automated beat detection, and fully automated measurement and stabilization. Based on Menlo Systems' figure 9® technology, this frequency comb is made for use in optics labs as well as other settings.

SMART-COMB can measure or stabilize CW lasers at wavelengths in the visible or near infrared. Feed in your laser and get the optical frequency with 14 digits of accuracy, or continuously stabilize your laser within a few hundred kHz over a period of days. SMART-COMB is also available with additional output ports at different wavelengths for applications where frequency comb light is used as seed light or for spectroscopy.

SMART-COMB has a robust design. Its performance has already been verified onboard of an aircraft and two sounding rocket missions, proving it is well-suited even for demanding environments.
