FZW Fizeau Laser Wavemeter
The MOGLabs FZW Fizeau Laser Wavemeter is a precision compact self-contained wavemeter: no host computer required. It measures from 350 to 1120nm with absolute accuracy better than 600MHz. Onunit display, ethernet and USB connectivity, and PID locking, are standard. Time-series measurements at up to 250 measurements per second can be plotted on the display or on a host computer. The device is easily integrated with common lab data acquisition systems using simple text commands, and wrappers for LabView, python and matlab.
