Bristol Instruments Extends Its Fast Wavelength Measurement Capability Further Into the Infrared 

VICTOR, NEW YORK  September 12, 2018 – Bristol Instruments, Inc., the leader in wavelength meter technology, has announced a new version of its 871 Series Laser Wavelength Meter. The new model 871B-NIR2 can measure the wavelength of lasers that operate out to  2.5 μm. These measurements have an accuracy of ± 0.75 parts per million (± 0.00075 nm at  1000 nm) 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 CW 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 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 excited to extend our fast wavelength measurement capabilities into the infrared,” said Dr. Brian Samoriski, Vice President of Sales & Marketing. “This new product will give more scientists and engineers the opportunity to take advantage of the reliable accuracy provided by Bristol Instruments.” 


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 products to reliably measure critical physical dimensions of materials such as specialty plastic films, medical tubing, and ophthalmic products.
