Coherent WaveMaster Wavelength Meter

Wavelength measurement of pulsed and CW lasers


The WaveMasterTM measures the wavelength of both CW and pulsed lasers of any repetition rate. The wavelength can be displayed in GHz, wavenumbers, or nanometres with vacuum and air readings available.

The WaveMaster will read the peak wavelength of sources as wide as 2nm from 400nm to 1095nm. Bandwidths wider than 2nm can be accommodated at the longer wavelengths.

The WaveMaster is easy to use. Just turn on the readout and get the beam within 10 degrees of normal incidence to the sampling probe. The probe has a 2-meter fiber-optic cable and takes up a minimum of beam path space.

Most intensity variances are automatically accommodated, but for the strongest and weakest signals, a front panel attenuator adjustment and intensity readout quickly afford accurate readings. No special triggering modes or setups are required for pulse capture.

The WaveMaster is portable with AC and battery power. The large, easy-to-read display is backlit and has adjustable contrast control for ease of use viewing. Configuration settings are maintained in memory and retrieved on start-up for convenience. Communication with the WaveMaster is also easy with a built-in RS-232 interface.
