The 871 Wavelength Meter is the best way to measure the absolute wavelength of both pulsed and CW lasers. It combines proven Fizeau etalon technology with automatic calibration. What’s more, a sustained measurement rate of 1 kHz enables the wavelength characterization of every single pulse for most lasers
Optical Laser Spectrum Analyzer - (OSA)
BRI-771 Series Laser Spectrum Analyzer
- (optional) fiber coupler for IR/MIR devices
- continuous calibration with built-in stabilized single-frequency HeNe laser
- accuracy: ±0.2 ppm (± 0.0002 nm @ 1000 nm)
- pulsed, CW and quasi CW (>10MHz)
- wavelength range: 375 nm – 14µm
- combined wavelength meter and spectrum analyzer
The Spectrum Anaylzer from Bristol Instruments
measures both, the wavelength and the emission spectrum including the side-mode suppression ratio. With spectral resolution up to 2 GHz, wavelength accuracy as high as ± 0.2 parts per million, and an optical rejection ratio of more than 40 dB, the model 771 provides the most detailed information about a laser’s spectral properties.
