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.
Bri-WDM-Wavelength meter
- wavelength range: 700 – 1680 nm
- CW and modulated signals
- Continuous calibration with built-in stabilized single-frequency HeNe laser
- measurement rate: up to 1 kHz
- Sensitivity: <-40dB (0.1 µW)
Bristol Instruments provides a family of optical
wavelength meters and multi-wavelength meters designed specifically for the testing of WDM lasers and WDM systems. Absolute laser wavelength is measured to an accuracy as high as ± 0.3 pm with a measurement rate as high as 1 kHz.
Wavelength measurement accuracy is guaranteed by continuous calibration with a built-in wavelength standard and is traceable to NIST standards.
