Burleigh WA-20 Wavelength Meter
Burleigh wavemeter measures the absolute wavelength of any CW laser operating between 0.4 and 4 µm. It's operation is entirely automatic, with the display being updated every 1.6 second to facilitate tuning a laser or monitoring is drift. The WA-20 measures the vacuum wavelength throughout the entire range of 0.4 µm to 1 µm. Accuracy is ± 1 part in 106 which is readout limited to 0.001 nm in the visible or 0.01 cm-1in the infrared.
The wavemeter is more accurate and easier to use for wavelength measurement than most grating spectrometers. It requires no external reference source for calibration anywhere within it's operating range.
