Test & Measurement

Optical wavemeter, optical spectrum analysers, spectrometers

Two of the key performance measures of an optical instrument measuring optical signal wavelength are its accuracy, and its ability to maintain it  over a long period of time. The way to achieve this accuracy and stability over time is through a highly stable optical frequency reference embedded in the instrument, in combination with software driven self calibration procedures. Due to the fact that TeraXion’s FSL laser module is locked to a gas molecule, it makes it a perfect fit for this application. Considering its long life expectancy and its ruggedness, TeraXion’s FSL can advantageously replace HeNe lasers commonly used as embedded reference in a wide variety of  scientific instruments.
