The 871 Series Laser Wavelength Meter from Bristol Instruments operates from 375 to 1700 nm measuring absolute wavelength of both pulsed and CW lasers. The device can measure wavelength to an accuracy as high as ± 0.75 parts per million. The system calibrates automatically with a built-in wavelength standard. The calibration process takes less than two seconds, and can be set to activate at a chosen time interval, or based on the system’s internal thermal conditions. It has fastest sustained measurement rate of 1 kHz resulting in time resolution of 1 ms. The meter requires an input as low as 20 nJ (20 µW at 1 kHz). The wavelength meter is available in a system that measures 89 mm x 432 mm x 381 mm and weighs 7.65 kg.
The 871 Laser Wavelength Meter is available in two broad wavelength configurations, VIS (375 - 1100 nm) and NIR (650 - 1700 nm). A pre-aligned fiber-optic input ensures optimum alignment resulting in uncompromised accuracy. The system operates with a PC running under Windows, via a 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.
