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 ¡¾ 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.

621 Series

CW lasers, 375 nm – 12 ¥ìm

The best way to determine the absolute wavelength of CW lasers is with the 621 Series Laser Wavelength Meter. This system provides real-time laser wavelength information measured to an accuracy as high as ¡¾ 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.

 

821 Series

Pulsed and CW lasers, 350 – 1700 nm

The 821 Series Pulsed Laser Wavelength Meter provides accurate wavelength information for researchers who need to know the exact wavelength of their CW laser, pulsed laser, or OPO. A unique Fizeau interferometer-based design measures absolute wavelength to an accuracy of ¡¾ 600 MHz. A built-in wavelength standard is used for automatic calibration to ensure greater confidence in the experimental results.

 

521 Series

CW lasers, 400 – 1700 nm, low-priced alternative

The 521 Series Laser Wavelength Meter is for scientists and engineers who need to know the absolute wavelength of their CW laser, but do not need to know it to the highest accuracy available. The model 521 is a unique system that couples accurate wavelength measurement and affordability in a compact instrument.
