Combines higher accuracy with the fastest measurement rate available.

VICTOR, NEW YORK – Bristol Instruments, Inc., the leader in wavelength meter technology, has announced a new version of its popular 871 Series Pulsed Laser Wavelength Meter. Wavelength can now be measured to an accuracy as high as ± 0.2 parts per million (± 60 MHz at 1000 nm). The model 871 also has the fastest sustained measurement rate of 1 kHz.

Featuring a unique Fizeau etalon design to measure laser wavelength of both pulsed and CW lasers, the model 871 calibrates automatically 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. The model 871 operates with a PC, running Windows, via standard USB and Ethernet interface. Measurement data can also be displayed anywhere in the lab on a tablet or smart phone, using a web-based application. In addition, an integrated proportional-integral-derivative (PID) controller benefits researchers who need active regulation of their laser’s frequency.

“We are pleased to offer even higher accuracy with the new version of the 871 Wavelength Meter, in addition to its unsurpassed measurement rate,” said Dr. Brian Samoriski, Vice President of Sales & Marketing at Bristol Instruments. These enhancements give our customers the most reliable accuracy, and utmost confidence in their experimental results.
