The 871 Series Laser Wavelength Meter from Bristol Instruments Inc. can measure the wavelength of lasers that operate out to 2.5 μm.
The measurements have an accuracy of ± 0.75 parts per million and are made at the fastest sustained rate of 1 kHz. The 871B-NIR2 Laser Wavelength Meter uses a unique Fizeau etalon design to measure the wavelength of both pulsed and continuous-wave lasers over the range of 1 to 2.5 μm. Automatic calibration with a built-in wavelength standard and pre-aligned fiber-optic input ensure uncompromised accuracy. The system operates with a PC via standard USB and Ethernet interfaces. Measurement data can also be displayed anywhere in the lab on a tablet or smartphone using a web-based application.
In addition, an integrated proportional-integral-derivative controller benefits researchers who need active regulation of their laser’s frequency.
