Fizeau Wavemeter (FZW)
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 (3σ). On-unit display, PID locking, ethernet and USB connectivity are standard. Time-series measurements at up to 500 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.
Matching fibre switches are available, with 4 and 8 input ports, and 4 or 8 analogue outputs with PID to wavelength-stabilise up to 8 lasers.
