Fast, accurate, and reliable pulsed & CW wavelength meters.

The 871 Series Laser Wavelength Meter from Bristol Instruments uses a proven Fizeau etalon design to measure the wavelength of pulsed and CW lasers to an accuracy as high as ± 0.0001 nm. The system generates a spatial interferogram that is detected by a fast photodetector array. An on-board digital signal processor quickly converts the interferometric information to wavelength resulting in a sustained measurement rate as high as 1 kHz.

Thanks to its all integrated technology, the LW-10 combines high performances and affordable price within a compact design. Its 20 MHz resolution and 200 MHz absolute accuracy makes it the perfect tool for tunable laser wavelength monitoring on the 630-1100 nm range for lasers such as Ti:Sapphire, DFB, ECDL.

	872 Series	The 872 Series Laser Wavelength Meter by Bristol Instruments features Fizeau etalon tech for high-resolution measurements, ideal for laser frequency stabilization. Available in two versions: 872A-VIS (375-1100 nm) and 872A-NIR (630-1700 nm). Both models offer ± 0.2 ppm wavelength accuracy (± 60 MHz at 1000 nm) and 1.0 ppb frequency resolution (300 kHz at 1000 nm). Automatic calibration ensures consistent performance for precise experiments.
	871 Series	The 871 Laser Wavelength Meter uses a proven Fizeau etalon design to measure the wavelength of pulsed and CW lasers to an accuracy as high as ± 0.2 parts per million (± 0.0002 nm at 1000 nm).

Laser 2000 offers pulsed & CW wavelength meters from both Bristol Instruments and Resolution Spectra.

Bristol Instruments was founded in 2005 by three technical and marketing leaders of the now-defunct Burleigh Instruments. Together, this group has over 80 years of combined experience in the design, manufacture, and marketing of lasers and precision test instruments used in basic and applied research, engineering, and production test applications.

Resolution Spectra Systems was set up in 2011 to develop an offer based on SWIFTS™ technology and advanced optical spectroscopy. Its founders are senior engineers, business managers and research scientists from high-technology companies and research laboratories from the Grenoble area in France. The company is also based in Meylan near Grenoble, one of Europe’s leading high-technology centres.
