Reliable Accuracy gives you greater confidence in your experimental results anywhere from the visible to the mid-IR
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 continuous calibration. Systems are available for CW and pulsed lasers that operate at wavelengths from 350 nm to 12 µm.
CW lasers, 375 nm – 12 μm
The best way to determine the absolute wavelength of CW lasers is with the 671 Series Laser Wavelength Meter. This system provides real-time laser wavelength information measured to an accuracy as high as ± 0.2 parts per million. This accuracy is guaranteed by continuous calibration with a built-in wavelength standard which ensures the reliable accuracy that is needed to generate the most meaningful experimental results.
