671 Series Laser Wavelength Meter

Optical Wavelength Meter by Bristol Instruments

Note: Your Quotation Request will be directed to Bristol Instruments.

The 671 Series Laser Wavelength Meter from Bristol Instruments uses a proven Michelson interferometer-based design to accurately measure the absolute wavelength of CW and quasi-CW lasers. It is available in four broad wavelength ranges - VIS (375 – 1100 nm), NIR (520 – 1700 nm), IR (1 – 5 µm), and MIR (1.5 – 12 µm). Two versions are available. The model 671A is the most precise, measuring wavelength to an accuracy of ± 0.2 parts per million (± 0.0002 nm at 1000 nm). For experiments that are less exacting, the model 671B is a lower-priced alternative with an accuracy of ± 0.75 parts per million (± 0.0008 nm at 1000 nm). The 671A system uses a single-frequency HeNe laser that is stabilized using a precise balanced longitudinal mode technique, to achieve the highest accuracy. A standard HeNe laser is used as the wavelength reference in the model 671B. This series is ideal for high-resolution laser spectroscopy, photochemistry, cooling/trapping, and optical sensing applications.

The 671 system operates with a PC running under Windows, via USB or Ethernet interface. Software is provided to control measurement parameters and to report data, or the system can become part of an experiment using a library of commands for custom or LabVIEW programming. In addition, a web-based application can be used to display or collect measurement data with a tablet or smart phone.
