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.

About

Phon

Features
Read full description

Phon is a sound level meter built like a measurement instrument, not a toy VU meter. MEASURE • Real-time dB SPL on an analog needle with a precise digital readout • A-weighting and Fast time constant, as defined in IEC 61672 • Session minimum, average and maximum • Per-model calibration for the built-in microphone, so readings mean something out of the box CALIBRATED EXTERNAL MICS Plug in a USB-C measurement microphone and Phon detects it instantly. Load the calibration file that came with your mic and Phon applies its measured frequency response and sensitivity to every reading. Built and tested with the Dayton Audio iMM-6C. Other USB-C measurement mics with an FRD-style calibration file should work too. PHON PRO — ONE-TIME PURCHASE • Calibration file loading for external mics • C and Z frequency weightings • Slow and Impulse time constants • Leq, the equivalent continuous level over the whole session • CSV export of the full session log, with timestamps, IEC 61672 column names and all calibration metadata Family Sharing supported. No subscription, ever.
