Wavelength Meters - Scientific

Bristol Instruments' wavelength meters are for scientists and engineers who need to know the exact wavelength of their lasers. These systems use proven interferometer-based technology to measure absolute wavelength to an accuracy as high as ± 0.0001 nm. To achieve the reliable accuracy that is expected from Bristol Instruments, all of its 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.
