Laser Spectrum Analyser, Wavelength meter

Numéro de référence fabricant :

771

Fabricant Bristol Instruments

Bristol Instruments

Description :

The 771 Series Laser Spectrum Analyser operates both as a high-accuracy wavelength meter and a high-resolution spectrum analyser resulting in the most complete spectral characterization of CW and pulsed lasers. Absolute laser wavelength is measured to an accuracy as high as ±0.2 parts per million, and the laser’s spectrum is determined to a resolution as high as 2 GHz. Continuous calibration with a built-in wavelength standard provides the reliable accuracy that is expected from Bristol Instruments.

The model 771 is available in several broad wavelength configurations to satisfy virtually any experimental requirement. These are the VIS (375-1100 nm), NIR (520-1700 nm), IR (1.3-5.0 µm), and MIR (2-12 µm).
