Bristol Instruments offers a large variety of optical interferometer-based products for wavelength measurements and laser spectral characterization. Spectrum analyzer, wavelength meter and linewidth analyzer for the entire range from the visible light to the mid infrared are rapidly available. Bristol Instruments offers the right solution for pulsed and CW-lasers, as well as for WDM lasers and systems.
ppm*: "parts per million", d.h. eine Genauigkeit von z.B. 0,2 ppm entspricht
internal calibration automatic with built in wavelength standard
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
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.
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.
