*inquire about different wavelength ranges


Frequency comb technology makes direct measurement of absolute optical frequencies possible. With the Mid-IR Comb system we have extended the wavelength coverage into the Mid-IR spectral region. The mode frequencies are completely defined by the repetition rate only, as the carrier envelope offset frequency vanishes in a difference frequency generation process. Such, the turn-key Mid-IR Comb is the perfect tool for high accuracy spectroscopy in the fingerprint region of many molecules.
