Qred AFBR-S20R1XX
Ultra-Compact NIR Spectrometer with Cooled
High-Performance Image Sensor
Overview
The Qred is the world’s first truly portable near-infrared spectrometer. On
a footprint smaller than a credit card, it includes high-throughput Czerny-
Turner optics with a TEC-cooled InGaAs image sensor. The advanced
thermal design provides high thermal stability and excellent heat transfer
without a fan. The rugged design with no moving parts ensures reliable
operation in rough environments. The Qred offers the following:
• Full processing of spectra in the device (offset, nonlinearity, dark
spectrum, and spectral sensitivity)
• Stable measurement conditions due to active cooled sensor
• AUX connector for analog and digital I/O, communication interfaces and
power supply

Application Software
Every Qred 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++, Delphi, LabVIEW, Matlab, and
Mathematica.
I/O Port
The Qred includes a new auxiliary
connector for analog and digital
I/O, communication interfaces and
power supply (if USB is not used).
The eight digital channels can be
configured as trigger input, shutter
or flash lamp control, process
control, or general purpose I/O
pins.
The Qred 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.
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.
