Bristol Instruments has announced several improvements to its 871 Series Pulsed Laser Wavelength Meter. The model 871, which excels with an unsurpassed measurement rate of 1 kHz, now has a wavelength accuracy as high as ± 0.75 parts per million (± 225 MHz at 1000 nm). In addition, an integrated proportional-integral-derivative (PID) controller benefits researchers who need active regulation of their laser’s frequency.

The 871 Pulsed Laser Wavelength Meter uses a unique Fizeau etalon design to measure laser wavelength of both pulsed and CW lasers. This performance is guaranteed by automatically calibrating with a built-in wavelength standard. The 871 system is available for operation from 375 to 1700 nm. Pre-aligned fiber-optic input ensures optimum alignment, resulting in uncompromised accuracy. Automatic pulse detection triggers data collection for asynchronous operation. It operates with a PC, running Windows, via standard USB and Ethernet interface. Measurement data can also be displayed on a tablet or smart phone using a web-based application.
