Bristol 871 Series Laser Wavelength Meter

The 871 Laser Wavelength Meter uses a proven Fizeau etalon design to measure the wavelength of pulsed and CW lasers to an accuracy as high as ± 0.2 parts per million (± 0.0002 nm at 1000 nm). Automatic calibration with a built-in wavelength standard guarantees this performance to ensure the most meaningful experimental results.

Features:

• Wavelength measured to an accuracy as high as ± 0.0001ppm

• Automatic calibration with a built-in wavelength standard

• Wavelength range options available from 375nm to 2500nm

• Sustained measurment rate of 1kHz

• Convenient pre-aligned fibre-optic input

• Straightforward operation with PC using high-speed USB or Ethernet interfaces

• Display software provided to control measurement parameters and report wavelength data

• Convenient table/smartphone application to report wavelength data anywhere in the laboratory

• Automatic wavelength reporting using custom or LabVIEW programming eliminates the need for a dedicated PC

• 5 year warranty

The 871 Laser Wavelength Meter generates a spatial interferogram that is detected by a fast photodetector array. An on-board digital signal processor quickly converts the interferometric information to wavelength. Because this calculation is done internally, a sustained measurement rate as high as 1 kHz is achieved.

Wavelength measurements can be reported at this rate by data streaming with an RS-422 serial interface, or an internal data buffer is available to save up to one million measurements.
