Applications

•Optimum for LD wavelength adjustment for DWDM due to

fast sampling measurement.

•Can be used as a wavelength standard for spectroscope calibration

due to high accuracy.

•Can be automated to measure the LD wavelength temperature

characteristics and wavelength current characteristics.

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 recalibration.

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.
