Bristol Instruments, Inc. has unveiled the 871 Series Laser Wavelength Meter. The system measures the absolute wavelength of pulsed and CW lasers. Its measurement rate of 1 kHz enables the wavelength characterization of individual laser pulses, and the resulting time resolution of 1 ms provides the most detailed wavelength analysis available of tunable lasers, the company asserts.
The 871 Laser Wavelength Meter uses a Fizeau etalon design to measure laser wavelength to an accuracy of ± 1 ppm (± 300 MHz at 1000 nm). This performance is guaranteed by automatically calibrating with a built-in wavelength standard, Bristol explains. The 871 system is available for operation from 350 to 1700 nm.
Pre-aligned fiber-optic input ensures optimum alignment, the company adds. Automatic pulse detection triggers data collection for asynchronous operation.
The model 871 operates with a PC, running under Windows, via standard USB and Ethernet interface. Measurement data can also be displayed using a web-based application on a tablet or smartphone.
"The new 871 Laser Wavelength Meter, with its 1-kHz measurement rate, will revolutionize many laser spectroscopy applications," said Dr. Brian Samoriski, vice president of sales & marketing at Bristol Instruments. "Our customers will realize greater efficiency and greater detail in their experiments."
