Burleigh WA-1500 Laser Wavelength Meter Wavemeter NIR 600-1800nm GPIB RS-232

The Burleigh (EXFO) WA-1500 NIR Wavemeter is a high-precision Michelson interferometer-based instrument designed for accurate absolute wavelength measurement of continuous-wave (CW) lasers across the near-infrared spectrum in laser characterization, fiber optic, and photonic research applications. It supports wavelength measurement accuracy of ±0.2 ppm (±50 MHz at 1500 nm) when laser spectral bandwidth is below 1 GHz FWHM, traceability to a built-in HeNe laser wavelength reference standard, automated environmental corrections for temperature, pressure, and humidity, both fiber-optic and free-space input options, and an analog output proportional to deviation from a specified setpoint, enabling precise laser stabilization, frequency monitoring, and real-time feedback control for tunable laser sources, DWDM transmitters, and spectroscopic measurements. With a benchtop form factor featuring a front-panel intensity bar graph display and standard RS-232 and GPIB interfaces for remote operation, it delivers dependable, ultra-high-accuracy characterization for advanced laser research, manufacturing, and metrology applications across NIR optical and photonic systems.
