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.
600 MHz (3σ) absolute accuracy, 350 to 1120nm
Built-in PID feedback with analogue output
Self-contained with colour display
wavelength range: 400nm to 1120nm
