Spectrometers
for Chemistry Applications
StellarNet miniature research grade spectrometers allow
for low cost measurements in the UV-VIS-NIR wavelength ranges.
These instruments can measure species absorption, emission,
fluorescence, transmission, concentration, and color, using
the free SpectraWiz® Software Suite. StellarNet Chemical
Absorbance Systems reliably measure absorbance and concentrations
and have applications in the food & beverage,
petrochemical, pharmaceuticals, raw material
industries.
|
StellarNets Low Cost UV-VIS Spectrometer system is
composed of the BLACK-Comet research grade concave grating
spectrometer, a SL5 high stability light source with integrated
cuvette holder, and an optical coupling fiber.
|
|
The
BLACK-Comet series of concave grating spectrometers
cover wavelength ranges 190-1100nm in four different configurations.
The BLACK-Comet utilizes aberration corrected optics allowing
for enhanced UV sensitivity, reduced stray light, uniform
resolution, and superb spectral imaging. |
|
The
RED-Wave NIR InGaAs series
spectrometers cover the near infrared 900-2300nminfrared wavelength
regions from 900-2300nm with either 512 or 1024 element cooled
photodiode arrays. StellarNets spectrometers are ruggedized,
durable, and the perfect instrument for any lab or field application. |

BLACK-Comet
& RED-Wave Spectrometer System with Dip probe measuring
from 200-2300nm.
|
A SL5
UV+VIS Light Source can be coupled via fiber optic cables
(2x F600-UVVIS-SR) to a cuvette holder and then to the BLACK-Comet
concave grating spectrometer for 200-1080nm detection.

Liquid Samples
For
liquids, samples can be pipetted inside cuvettes and then placed
into the CUV1 (4-way fiber optic cuvette holder) used
for transmission, absorbance, fluorescence, and color measurements.
You may also use the DPH fiber optic dip probe for
in situ measurements or our ATR probe for darker colored
inks and dyes. A variety of flow cells and industrial probes
for process monitoring applications are also available. |
|
MFC
is a mini flow cell with 10mm optical path length with fused
silica windows (optional Ultem, Plexiglas, Steel, Teflon or
PEEK). Optional 2.5, 5, 10, 20, 50 and 100-mm optical path lengths.Flow
Cell
MFFC
is a mini fluorescence flow cell that has a fiber optic cable
input to send excitation energy through a fused silica window
into a 2-mm inner-diameter sample compartment. Emitted energy
is collected by a second fiber, oriented at 90°, that
connects to a spectrometer configured for fluorescence.
|
|
CUV-TEMP
is a temperature controlled cuvette holder for fluorescence
& absorbance measurements from -30 °C to +105 °C.
Includes sample compartment, two imaging lenses, two collimating
lenses, two mirror plugs, submersible pump, cover with access
cap, tubing, cables and a stir bar. |

The
RPH Reflectance probe is a popular accessory for color
measurement. The SL1-Filter Tungsten Halogen lamp with internal
Color Equalization Filter (CEQ) is used to illuminate the RPHs
7 input optical fibers. At the probe tip the 7 optical fibers
are bundled around one 600um collection fiber which returns
the reflected light to the spectrometer. The RPH probe can be
used with the RPH1 Reflectance Probe Holder block that
maintains a 45 degree angle and user set distance from sample
or the RPH3 is a Reflectance Probe Holder stand for 90°
angle measurements. The RS50 white reflectance standard should
be used to take your white reference spectrum for all color
measurement applications. |
|
The
RTIP45 is a black plastic tip has 45 degree angle and
slides onto reflectance probe and locks to set position. |
|
An integrating sphere,
such as the IC2, can also be used in place of the fiber optic
reflectance probe to improve measurement consistency. The IC2
has an illumination port as well as a baffeled collection port.
Coarse Samples
The RFX-3D Reflectance fixture has integrated light source
to enable simple color measurement of solids and powders StellarNet
3-D Reflectance Fixtureby placing sample on directly on top.
Additionally the RFX-3D has 3 fiber connectors to the spectrometer
each positioned 120 degrees in a circle thus eliminating the
need to rotate coarse grain samples. Reflectance from 3 positions
is combined using special 3-to-1 fiber for spectrometer. |
