Bristol Instruments Now Offers a High Accuracy Laser Wavelength Meter for Mid-Infrared Applications

VICTOR, NEW YORK September 8, 2023 –Bristol Instruments is pleased to announce a new addition to its 671 Series Laser Wavelength Meter product line. The new model 671A-MIR supports the characterization of free-space, mid-infrared lasers operating in the 1.5 to 12 μm spectral range with an accuracy performance up to ± 0.2 ppm.

Building on Bristol’s unique strength in characterizing lasers in the mid-infrared, the new model 671A-MIR brings our highest accuracy performance to the MIR detection range. Ideal for scientists and engineers who need to know the exact wavelength of their CW lasers, the 671A-MIR can provide ± 0.2 ppm accuracy in the 1.5 – 5 μm spectral range and ± 1 ppm accuracy from 5 to 12 μm.

As with all 671 Series Laser Wavelength Meters, the new 671A-MIR includes a built-in, continuous calibration laser source. Each measurement is calibrated every time and ensures confident results now and for years to come.

“The 671 Series of Laser Wavelength Meters support the broadest spectral range of CW lasers.” said Nick George, Marketing Manager at Bristol Instruments. “With the enhanced accuracy and detection range of the new model 671A-MIR, our customers experience uncompromised mid-infrared laser wavelength measurements to satisfy their most demanding applications.”

About Bristol Instruments

Since its founding in 2005, Bristol Instruments has solely focused on designing, manufacturing, and marketing precision instruments using its expertise in optical interferometry. Bristol’s flagship products accurately characterize the wavelength and spectral properties of lasers and are used by scientists and engineers at universities and government and industrial laboratories. They are also used for the development and production testing of laser transmitters used in optical fiber communications. In addition, Bristol Instruments provides interferometer-based Thickness Gauge products to measure critical physical dimensions of materials reliably and non-destructively such as: lens assemblies, display components, and ophthalmic products.
