Improved World-class Optical Performance

Standard and High-performance models

There are two models available, Standard and High performance.

The High performance model provides even higher wavelength

accuracy and dynamic range.

High wavelength resolution: 0.02nm

High wavelength accuracy: ±0.01nm

• High performance model: ±0.01nm (C band)

• Standard model: ±0.02nm (C+L band)

Ultra-High dynamic range: 78dB typ.

With the reduced stray-light in the monochromator, AQ6370C

achieves ultra-high dynamic range of typ. 78dB.

Sharper fi lter edge

The high performance model can also achieve a higher dynamic

range within 0.2nm of the peak wavelength. With the sharper

spectral characteristics of the monochromator, spectral signals in

close proximity can be separated clearly and measured accurately.

Stray-light suppression ratio: 80dB typ.

This new specifi cation provides stray-light suppression capability

without the High dynamic mode, which takes a longer measurement

time.  The AQ6370C contributes to shortening the measurement time

with the high stray light suppression ratio.

Wide level range: +20dBm to -90dBm

The AQ6370C can measure high power sources such as optical

amplifi ers and pump lasers for Raman amplifi ers, and very weak

optical signals as well. Measurement sensitivity can be chosen from

seven categories according to test applications and measurement

speed requirements.
