Spectrometers
for Color Measurement
These instruments measure the color of solid and liquid
samples using either a fiber optic reflectance probe, sample
fixture, flow cell, dip probe, or cuvette holder. Theyre
great for use in the lab, field, or on-line/at-line production
environments. Finally, the solution youve been looking
for! Color quality control is now affordable with a StellarNet
Color Measurement system.

Modular
Systems
StellarNet Modular Color Measurement Systems include a miniature
spectrometer, light source, and accessory depending on your
sample type. The StellarNet BLACK-Comet-CXR spectrometer has
consistent resolution throughout 280-900nm and is a perfect
low cost instrument for any color measurement application.
As one of StellarNets concave grating models it has
low stray light levels because there are no mirrors in its
optical bench. It is engineered with no moving parts which
results in shock proof durability, permanent alignment, and
a ruggedness unmatched by any spectrometer in its field. |
Integrated
CASE Systems
The StellarCASE-Color integrated portable case system includes
interior mounting of spectrometer instrumentation pre-configured
for Open & Measure application with no additional
setup required. The system includes a top mounted tablet with
pre-installed Real-time spectrometer operating software for
CIELAB colorimetry & dE color difference measurement.
Internal main power control system with ON, OFF, & Charge
buttons. The pre-configured spectrometer equipment is covered
with an acrylic sampling surface and the sampling fixture
head for easy measurement & clean-up. The system battery
has 8 hour lifetime for field and portable application. StellarCASE-NIR
also available for NIR applications. |

StellarNet
Color Measurement Systems reliably measure CIELAB &
Delta E* values. Applications include color measurements
of food, beverages, industrial liquids,
textiles, plastics, pharmaceuticals,
and raw materials.

SL1-Filter tungsten halogen lamp, R600-8-VisNIR reflectance
probe, RS50 white reflectance standard, RPH probe holder, and
SpectraWiz Spectroscopy Software. |

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.
Translucent
Samples
The TXF-4
transmission fixture includes two collimating lenses which
allows the sample to be oriented vertically as shown above.
Custom posts can be designed to increase pathlength Interchangeable
parts allow the TXF-4 to be easily converted into the RPH-3
using the same base and stand.
|
|
For measuring
the transmission of thick or multi-layered such as bulletproof
glass or curved samples such as lenses where light scattering
may be present the TXF-IC2 is recommended. The TXF-IC2
includes 1 collimating lens and 1 miniature 2'' integrating
sphere with 5/8'' 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.
|
|
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.

RED Horseradish= L*=15.83, a*=29.598, b*=6.006
The BLACK-Comet-CXR 280-900nm, RFX-3D reflectance fixture, and an
optical fiber can be used to measure the CIELab color of many types
of samples. Simply place into a petri dish and set on top of the fixture.
The RFX-3D collects diffuse reflectance from 3 different angles on
a 1? spot and is great for non-uniform and coarse grain samples!

BLUE CHICK PEEP= L*= 66.36, a*= -22.104, b*=-36.68
A StellarNet low cost spectrometer can easily be configured for colorimetry
using a light source and a reflectance probe. The built in CIELAB
app in the SpectraWiz software can measure quantified color data in
milliseconds. These spectrometer systems are used for quality control,
research, and production of food and beverages worldwide. Color consistency
and control can be applied to many other industries and applications.
