Beschreibung
The Advantest Q8326 is an optical wavelength meter capable of high accuracy and high resolution measurement at the central wavelength of the light from laser diodes (LD) for DWDM. Using a He-Ne laser as the reference wavelength and the Michelson interference method for measurement, it assures a high accuracy measurement. This unit even provides a high sampling rate of 5 times per second, and is suitable for adjustment of oscillation wavelength from laser diodes for DWDM. Wavelength variation can also be measured with high resolution and high accuracy using a deviation display function. The Q8326 can measure wavelengths at a sampling speed of five per second so that wavelength fluctuations caused by tem-perature variations can be captured precisely.
