YOKOGAWA AQ6375 LONG WAVELENGTH OPTICAL SPECTRUM ANALYZER

High Performance LONG WAVELENGTH
The AQ6375 is the first bench-top optical spectrum analyzer covering the long wavelengths over 2 μm.
It is designed for researchers and engineers who have been struggling with inadequate test equipment to measure in these long wavelength ranges. The AQ6375 achieves high speed measurements with high accuracy, resolution and sensitivity, even while providing full analysis features. Troublesome calibration steps and the development of external analysis software is no longer required.

The features of this AQ6375 are indispensable to the research, development, and manufacturing of optical devices in the wavelength range from telecom band to 2.4 um. No other test system can achieve this high performance and ease of use at the same time.

Long Wavelength 1200 nm to 2400 nm

The AQ6375 covers not only telecommunication wavelengths, but also the long wavelength region which is used for environmental sensing, medical, and industrial material applications.

High Sensitivity +20 dBm to -70 dBm

The AQ6375 can measure optical power as low as -70 dBm, which enables measurements of low power sources or low power output of a device under test.Measurement sensitivity can be chosen from seven categories according to test applications and measurement speed requirements.

High Resolution & Wide Dynamic Range

The AQ6375 uses a double-pass monochromator structure to achieve high wavelength resolution (0.05 nm) and wide close-in dynamic range (55 dB). Thus, closely allocated signals and noise can be separately measured.

High speed Measurement

GREATER EFFICIENCY

High Speed Sweep
With a proprietary sweep technique the AQ6375 achieves a much faster sweep speed than conventional measurement systems which use a monochromator. Max. sweep time is only 0.5 sec. in 100 nm span.

Fast Command Processing and Data Transfer
Applying a fast microprocessor, the AQ6375 achieves very fast command processing speed and Ethernet provides up to 100 times faster data transfer speed than the GP-IB.

Measurement Examples

Free-Space Optical Input

SUPPORT MULTIMODE FIBER

Applicable fiber: SMF and MMF

The AQ6375 uses a free space input structure, not having an optical fiber inside the monochromator, that can handle both single mode and multimode fibers. The free space input is also beneficial for measurement repeatability.

Built-in Calibrator

EASY CALIBRATION

The AQ6375 comes with a built-in calibrator for wavelength calibration and optical alignment adjustment of the monochromator in order to maintain accurate measurements. The calibration and adjustment are automatically performed and completed within a couple of minutes.

Wavelength Calibration

Calibrates with the designate absorption line of Acetylene gas.

Optical Alignment Adjustment
Corrects mechanical movements inside the monochromator caused by shock and vibration.

Note: the wavelength can also be calibrated with an external light source.
