High precision optical wavelength meter (for CW only/for both CW and pulse) 871 series
Japan Laser Co., Ltd.
About This Product
■High precision CW & pulse wavelength meter “871 series”
The 871 series laser wavelength meter measures the wavelength of pulsed and CW lasers with high accuracy of ±0.0001 nm. Generate interference fringes from the received signal of a high-speed photodetector array. An onboard digital signal processor quickly converts interference information into wavelengths and maintains measurement rates as high as 1 kHz. There are two versions: the high-precision 871A model and the low-priced 871B model.
■Features
・High wavelength accuracy: ±0.0001nm (varies depending on model)
・Automatic calibration
・Wide measurable wavelength range: 375nm to 2.5μm
・High resolution: ±0.1ppm (varies depending on model)
・High-speed measurement rate: 1kHz
・Pre-aligned fiber input connector
・Synchronized measurement with automatic pulse detection
・Built-in PID controller: Applicable to laser wavelength stabilization
・USB or Ethernet interface
・Control program for Windows-based PC: Can be controlled with any PC
■Application example
・High resolution laser spectroscopy
・Photochemistry
・Cooling/trapping of atoms and molecules
・Light sensing
