Optical spectrum analyzer with an Ultra High Close in Dynamic range

www.apex-t.com - APEX Technologies Optical Spectrum Analyzers achieve more than 83 dB of dynamic. They also have the unique advantage to have this high dynamic really close to the peak. For example, when the best standard grating based OSA can achieve 78 dB at +/- 1 nm, APEX Technologies AP2040 series can achieve 80 dB at +/- 6 pm from the peak.
