MWM Laser Wavemeter
The MOGLabs Laser Wavemeter is a precision compact laser wavelength measurement device, and optical spectrum analyser, with on-unit display and ethernet/USB connectivity standard. Unlike interferometric wavemeters, our device clearly reveals multimode laser operation, making it particularly suitable for use with external cavity diode lasers and atom cooling and trapping experiments. At prices so low you can afford to put a wavemeter on every laser in your lab, to know when your laser is unlocked or multimoding.
