Now in its 6th generation, the MOGLabs MWM Economical Wave Meter is a compact and economical grating-based laser wavelength measurement device, and optical spectrum analyser, with an integrated display and ethernet/USB connectivity. Use it standalone or with the Windows GUI software package included.
A compact laser wavelength measurement device, with on-unit display, and ethernet/USB connectivity standard. Unlike interferometric wavemeters, the Moglabs MWM device clearly reveals multimode laser operation, making it particularly suitable for use with external cavity diode lasers and atom cooling and trapping experiments. Units are supplied calibrated at user-defined wavelength (e.g. 775nm to 797nm), and can then be adjusted to other wavelengths in the range 350nm – 1100nm with user-calibration.
