High speed Measurement

- GREATER EFFICIENCY -

High Speed Sweep With 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

1800nm DFB-LD Resolution: 50 pm, Span: 10 nm Sensitivity: HiGH1/CHOP	2010nm DFB-LD Resolution: 50 pm, Span: 20 nm Sensitivity: HiGH1/CHOP

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 multimode fibers. The free space input is also beneficial for measurement repeatability.

Structure of the optical input

Built-in Calibrator

- EASY CALIBRATION -

The AQ6375 comes with the 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.
