World-class optical performance

High resolution and high dynamic range

The advanced monochromator achieves high wavelength resolution and a large close-in dynamic range. Thanks to the monochromator’s sharper spectral characteristics, spectral signals in close proximity can be clearly separated and accurately measured.

High sensitivity

Weak optical signals can be measured accurately and quickly.

7 sensitivity settings

Sensitivity can be selected according to the test applications and the measurement speed requirements.

High dynamic range mode

Achieves a better dynamic range by reducing the influence of stray light that occurs when the input signal is a strong optical signal.

Pulsed light measurement

Peak-Hold and external trigger mode

Measure the peak spectrum of a pulsed light signal. Frequently used in transmission-loop tests of telecommunications systems, as well as in low-power measurement in the early stage of laser chip development to capture the peak power of a pulsed signal.

Excellent performance

Fast sweep

Thanks to the advanced monochromator, faster electronic circuits and noise-reduction techniques, the AQ6373B achieves a high measurement speed even when measuring a steep spectrum from DFB-LD signals or when measuring a low-power signal from a broadband light source.

Wide span while maintaining high resolution

50,001 data sampling points expand the measurement range in a single sweep while maintaining high wavelength resolution. This makes measurements easier and more efficient than conventional systems, which use a small number of sampling points and require multiple partial measurements to cover the full wavelength range.

Easy to maintain

Changes in ambient conditions, vibration and shock associated with an optical-precision product such as an optical spectrum analyzer will affect the optical components and ultimately degrade the optical performance.

Using its standard functions, the AQ6373B can maintain high optical performance within a few minutes, so you can quickly start measuring.
