Wavelength Meter Using He-Ne Laser as Reference Wavelength

The Q8326 is an optical wavelength meter that

measures an emission center wavelength with high resolution.

The Q8326 uses a He-Ne laser for the reference

wavelength and uses the Michelson interference

method to enable high accuracy measurement.

This wavelength meter achieves

fast sampling (five per second) which is optimum

for oscillation wavelength adjustment of

LD for DWDM. With the deviation display

function, wavelength fluctuations can also be

measured with high resolution and accuracy.

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.
