How does it
work ?
The
FTIR-Rocket uses the so-called self compensated pendulum Interferometer.
This means that off-axis movements created by vibrations or
temperature variations of the mirrors are compensated in two
arms of the interferometer and the optical path difference
(which is relevant for calculating the spectra) is unaffected by
these vibrations.
so these kind of architectures (which are now commonly used in
FTIR systems) are relatively insensitive to vibrations or
temperature variations. For controlling the movement of the
mirrors a solid state temperature controlled laser is coupled
into the interferometer. Compared to classic HeNe laser these
telecom lasers are cost-effective, compact and less demanding in
maintenance..
The FT-NIR
Rocket has a SMA connector for a fibered light input. It is
ideal for making fibered measurement setups. It can be used in
combination with the same accessories (cuvette holder, halogen
lamp or reflections probes) as the standard grating
spectrometers. Ideally the spectrometer should be connected with
0.6mm core diameter NIR fibers. A 10-20W halogen lamp as light
source is sufficient for most applications.

Features and benefits
Self compensated Interferometer principle:
-
The multipass self compensated interferometer
presents an optimal configuration for miniaturization
-
Thanks to its
symmetry the interferometer remains stable with temperature
variations and vibrations.
-
Alignment of the device is
simple and robust.
-
Solid state laser control
makes device compact and reduces maintenance costs. No high
voltage driving as for He Ne lasers.
Optional parameter:
Variable gain
and resolution permit to optimize
measurement parameters.
Attractive pricing
:
Since the FT-NIR Rocket uses few small optical elements based
on a relatively low cost technology.
More cost-effective solutions than ever possible before.
Software
The FT-NIR-Rocket is delivered with a free windows XP,2000, windows 7 (32 and 64 bits) compatible program
(basic software package). Also light version for windows CE is available.
The FT-NIR can be connected via ethernet or USB to a laptop computer or to a
compact embedded computer with windows CE.
Basic software
Package includes
- Display
real time spectral measurement results

In
collaboration with
LABCOGNITION in Germany we offer the following optional software
packages:
IRAnalyze software
package:
is a high sophisticated IR spectrum
interpretation tool. Based on an IR spectrum it provides you
with automatic results for IR bands to functional group
correlations and their characteristic frequencies. Furthermore
it is a comprehensive electronic dictionary to browse
frequiencies for correlated IR bands.
Math Add-on module:
contains a set of standard manipulation
operations used in spectroscopy, like normalization, derivative,
baseline correction, peak picking and more.
In addition some special operations are available, like
multiplicative scatter correction, thickness correction or
standard normal variate correction and others.
Quantity Add-on module:
is an expert in multivariate data analysis with
quantitative methods like PLS and MLR. A convenient and
intuitive wizard guides your through all steps of calibration
model development. Complex statistical methods become very easy
to use even for non-experienced users.
Search Add-on module:
is an ideal add-on to archive your spectroscopic
data and related information. It includes spectrum and full text
search functionality on spectral libraries of various different
library formats or directly on data in the file system.
USB Infrared lamp:
The
Arcoptix USB lamp is a compact usb powered lamp. The USB
lamp features a SMA 905 connector for easy coupling in optical fibers.
The lamp can via fibers be connected to a sample holder, reflection
probe or to an integration sphere.
The USB lamp features also a smart power control for high lamp
stability, a mechanical variable shutter for power output control and
an integrated cuvette or filter holder. the USB empowering makes the
lamp ideal for on the field spectral measurements.
The USB lamp is
available in two versions one optimized for VIS-NIR. Notice there
exist also a version for the MIR region:
