Wavelength measurement accuracy of ± 0.1 nm

Measurements are accurate to ± 0.1 nm (1.3 µm) using the built-in He-Ne laser as a reference light source.

As a result, accurate wavelength measurements can be made without wavelength calibration.

Maximum wavelength range of 0.05 nm

The Q8344A has a maximum resolution of 0.05 nm at short wavelengths (0.85 µm),

making it possible to measure CD and visible laser diodes in fully resolved oscillation mode, one by one.

Large-diameter fiber input (option)

An optional 200 µm large aperture input is available.

This option is required when analyzing devices with wavelengths larger than the standard fiber aperture (GI 50 µm).

For laser diode analysis, the standard 50 µm size is recommended,

while for LED analysis, this optional size is recommended.
