Qwave AFBR-S20W1XX
Compact USB Spectrometer Combining
Excellent Technical Specifications with
Outstanding Spectroscopy Software
Overview
With its focal length of 75 mm, the Qwave offers technical specifications
that you would normally expect to find in much larger spectrometers.
Combined with our unique spectroscopy software, Waves, it is the ideal
spectroscopic instrument for applications that require a resolution of 0.2 to
0.5 nm and a numerical aperture of up to 0.10.

Application Software
Every Qwave spectrometer includes
Waves user software developed
for general-purpose spectroscopy
applications. Waves includes
sophisticated algorithms for data
acquisition and evaluation, which
provides the following features
through a clear and straightforward
user interface.
• Take and display series of spectra
• Automatic exposure control with
dark spectrum interpolation
• Import most ASCII-based file
formats
• Export as ASCII table to almost
any numerical analysis software
• Comprehensive tools for
displaying and analyzing spectra
• Strip charts for comparing
characteristic values between
multiple spectra including peak
follower in real time
• Graph printing and export to PDF
• Dynamic peak finder (no need to
set a threshold level)
• Dark spectrum interpolation
• Transmission, absorption, and
reflection measurements
• Colorimetry
Waves is very easy to use and
very intuitive. Various spectrum
evaluation options are available
with minimal effort and only a
few mouse clicks. For example, to
zoom in, adjust the zoom slider. To
move around, adjust the scrollbar.
To change the x-axis unit, select
the corresponding button. Values
such as peaks or colorimetry are
instantly calculated as soon as
a spectrum is taken. Waves is
available as a free download from
our website.

Software Library
A software development kit (SDK)
is also included to control the
spectrometer and take spectra
from your own software. It consists
of a Windows DLL library for the
.NET framework, documentation,
and sample code. The SDK can
be used with any programming
language that can use .NET DLLs,
including C#, Visual Basic .NET,
C++/CLI, Delphi, LabVIEW, Matlab,
and Mathematica.
I/O Port and Trigger
The Qwave includes four I/O
channels that can be configured
as trigger input, shutter and light
source control, or general purpose
I/O pins.
The Qwave supports three trigger
modes: software trigger, interval
trigger, and external trigger. It can
be set to trigger on the start or the
end of the exposure period. For
synchronizing the Qwave precisely
to external events, a special low-
jitter mode is available.
Communication Protocol
The spectrometer can also
be directly controlled from an
embedded microcontroller or
other operating systems using the
device communication protocol.
Just like our application software,
the protocol is designed to be
both powerful and easy to use for
software developers.
