FZW Fizeau Laser Wavemeter or equivalent

A compact wavelength measurement device, providing reliably accurate measurements over a wide range of wavelengths (350-1120nm) without recalibration, and up to 1280nm on request. The measurement and calculation is performed on the device, with the result displayed on the screen; no need for a host computer.

Equipped with ethernet and USB interfaces to allow for integration into existing control systems (LabVIEW, MATLAB and python drivers provided) using simple text-based commands.  A simple one-button recalibration procedure using an external reference source compensates for any long-term drift. External triggering and wide bandwidth mode allow use with pulsed lasers.
