Bristol Instruments Expands Capabilities Of Its 871 Series Pulsed Laser Wavelength Meter

Notable enhancements include higher wavelength measurement accuracy and a built-in PID controller.

VICTOR, NEW YORK – Bristol Instruments, Inc., the leader in wavelength meter technology, 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. The model 871 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.

“The 871 Pulsed Laser Wavelength Meter already benefits our customers with a sustained measurement rate of 1 kHz, the fastest available,” said Dr. Brian Samoriski, Vice President of Sales & Marketing at Bristol Instruments. “Now, they can utilize this speed to automatically stabilize their lasers more precisely.”
