871 System

Bristol Instruments, Inc., a specialist in wavelength meter technology, 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.
