Bristol Instruments Introduces Wavelength Meter for Pulsed Infrared Lasers

The wavelength of pulsed lasers that operate from 1.5 to 5 μm can now be measured with reliable accuracy.

VICTOR, NEW YORK January 24, 2012 – Bristol Instruments, Inc., the leader in laser wavelength measurement technology, has introduced a new laser wavelength meter for researchers who need to know the exact wavelength of their pulsed infrared lasers and OPOs.

The new model 821B-IR is designed to operate over the entire wavelength range of 1.5 to 5 μm. Proven Fizeau interferometer-based technology is used to measure the absolute wavelength of pulsed and CW lasers to an accuracy as high as ± 0.004 nm. To achieve the reliable accuracy for which Bristol Instruments is known, the system is automatically calibrated with a well-known wavelength standard. What’s more, a measurement rate of 200 Hz and other features allow for convenient integration into an experiment to provide real-time wavelength data.

“The spectral region of 3 to 5 μm is important to a variety of applications such as molecular spectroscopy and chemical and environmental sensing,” said Dr. Brian Samoriski, President of Bristol Instruments. “Since pulsed lasers are used for many of these applications, the new 821B-IR Pulsed Laser Wavelength Meter provides the ability to accurately measure laser wavelength and therefore ensure more meaningful experimental results.”
