Precise wavelength meters for researchers who need to know the exact wavelength of their lasers.

Our wavelength meters use proven interferometer-based technology to measure absolute wavelength to an accuracy as high as ± 0.0001 nm. To achieve the reliable accuracy you depend on, all of our wavelength meters include a built-in wavelength standard for calibration.

Systems are available for CW and pulsed lasers that operate at wavelengths from 375 nm to 12 µm.
