The 721 series provides the most complete analysis because it operates as both a high-accuracy laser wavelength meter and as a high-resolution laser spectrum analyzer.
Wavelength measurement and spectral analysis with one instrument.

Features:
• Absolute wavelength accuracy as high as ± 0.2 parts per million.
• Spectral resolution as high as 2 GHz.
• Operation available from 375 nm to 5.0 μm
• Operation with CW and high-repetition rate pulsed lasers (pulse width >50 ns, repetition rate >50 kHz)
• Input power requirement as low as 10 μmW
