The Application provides easy to use access for HighFinesse/Ångstrom Wavemeter for monitoring pulse and CW-lasers (for more info, please visit our address: https://www.highfinesse.com/en/wavelengthmeter/index.html). Connection to a device is provided through TCP/IP protocol in a local network. The main screen presents all necessary information about measurements as wavelength and intensity of the signal for each device channel. When there is no possible way to see the Application screen during laser tuning, the Application can continue to work in an acoustic mode when a changing wavelength generates the tone.
