General Meters : Advantest Q8326

The Q8326 is a 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, the Q8326 assures a high-accuracy measurement. The Q8326 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.

High Resolution


The Michelson interference method allows high resolution measurements of up to 0.001 nm/100 MHz.
High Accuracy Measurements


Use of a He-Ne laser for the reference wavelength enables high accuracy measurements of up to 2 ppm. In addition, since the He-Ne laser oscillates with high stability, a 2 ppm measurement accuracy is guaranteed over a long time period without recali-bration.
Wide Bandwidth


The measurement range covers short wavelengths of 480 to 1000 nm and long wavelengths of 1000 to 1650 nm and is selectable via a single switch operation.
High-speed Sampling
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.
