The products offered by Bristol Instruments enable researchers at universities, government laboratories, and industry who are involved in a number of fields including chemistry, physics, and optics. In particular, Bristol Instruments supports scientific applications such as high-resolution laser spectroscopy, photochemistry, optical cooling/trapping, chemical/environmental sensing, and laser development.

Bristol Instruments’ laser characterization products precisely analyze a laser’s wavelength and spectral properties. The flagship capability includes a family of wavelength meters that provide accurate information for scientists and engineers who need to know the exact wavelength of their laser. This is especially important for researchers who use tunable lasers and laser diodes. Since the wavelength of such lasers is not known a priori, wavelength measurement, with the reliable accuracy that is provided by Bristol Instruments, ensures the most meaningful experimental results.

Bristol Instruments also offers a unique laser spectrum analyzer that operates as both a high-accuracy wavelength meter and a high-resolution spectrum analyzer. This product measures absolute laser wavelength and spectral parameters such as linewidth and longitudinal mode structure. The result is the most complete spectral characterization available.
