Exfo-Burleigh WA-1650 Wavemeter optical wavelength meter is designed for simple, automatic and accurate wavelength measurement of continuous wave (CW) and modulated laser sources. The WA-1650 has microprocessor-based electronics that allow accurate counting and analysis of interference fringes. The microprocessor computation automatically corrects for the refractive index of air, using data from built-in temperature and pressure sensors and converts the resulting measurement to units of nm or GHz. The microprocessor also makes it possible for the WA-1650 to calculate and display the deviation between the measured wavelength and starting point, or compute the average of up to 128 measurements.
