| AQ6373 Visible Wavelength Optical Spectrum
Analyzer |
| |
|
Overview
The AQ6373 is one of the latest additions to the AQ6370 Series of
Optical Spectrum Analyzers. With the ability to provide high speed,
accurate analysis of the short wavelength range between 350nm and
1200nm, this OSA is well suited for a broad range of applications.
The AQ6373 can accelerate the development and manufacturing of short
wavelength lasers, passive devices and LEDs as well as equipment
that uses these devices for the biomedical, material processing,
consumer product and telecommunications markets. With built in color
analysis capabilities and remote command compatibility the AQ6373
provides an upgrade of capabilities, speed and performance for
current AQ6315 users.

World-Class Optical performance |
|
High Resolution and High Dynamic Range
The advanced monochromator achieves high wavelength
resolution and high close-in dynamic range. With the sharper
spectral characteristics of the monochromator, spectral
signals in close proximity can be separated clearly and
measured accurately.
High Sensitivity
Weak optical signals can be measured accurately and quickly.
Seven Sensitive settings
Can be selected according to test applications and
measurement speed requirements.
High Dynamic mode
Obtains a better dynamic range by reducing the influence of
stray-light, which is caused when the input is a strong
optical signal.
|
|
Pulsed
Light Measurement |
|
Peak-Hold and External trigger mode
Measure a pulse peak spectrum of a pulsed light signal.
Often used in the transmission loop testing of
telecommunication systems, and also in the low power
measurement at the early stage of laser chip development to
catch the peak power of a pulsed signal.
|
|
Free Space Input |
- Multimode and
single mode fiber on the same OSA.
- Small insertion
loss variation at the input
connector increases measurement
repeatability.
- No damage
connecting fibers
because there is no physical contact.
- Supports SM, GI
(50/125 µm, 62.5/125
µm) and
large core fiber up to 800 µm.

Excellent Efficiency |
|
Fast Sweep:
With an advanced monochromator, faster electrical circuits,
and noise reduction techniques, the AQ6373 achieves fast
measurement speed even when measuring a steep spectrum from
DFB-LD or DWDM signals, or when measuring a low power signal
from a broadband light source.
Fast Remote Interface
-
The AQ6373 provides faster remote
control and data transfer capability.
-
100x Ethernet interface is 100
times faster.
-
10x GP-IB interface is 10 times
faster (than previous models).
Wide Span Sweep yet High Resolution
The 50,001 data sampling points expands measurement range in
a single sweep while keeping a high wavelength resolution.
This makes your measurement easier and more efficient than
conventional systems that use low number of sampling points
and require multiple partial measurements to cover the
complete wavelength range..
|
|
Easy to
Keep Accurate |
|
Ambient condition change, vibration and shock to an optical
precision product, like an optical spectrum analyzer, will
effect the optical components and eventually degrade optical
performance. Using standard functions, the AQ6373 can
maintain its high optical performance within a couple of
minutes so that you can quickly start a measurement.
Optical alignment function
Automatically aligns the optical path in the monochromator
using the built-in source to maintain high performance.
Wavelength calibration function
Automatically calibrates the spectrum analyzer with an
external light source, to ensure the wavelength accuracy.
Built-in optical alignment source
GI 50/125µm fiber is required.
An external light source is required for wavelength
calibration
Please Note: There are
cases that the optical alignment and wavelength calibration
function cannot correct optical performance. Periodical
calibration is also required. |
