BLACK-Comet-CXR
SpectroColorimeters
Instruments for Color Measurement
These instruments measure the color of solid
and liquid samples using
either a fiber optic reflectance probe, fixture, dip probe, or cuvette
holder. The
StellarNet BLACK-Comet-CXR colorimeter has consistent resolution
throughout 280-900nm and is a perfect low cost instrument for any color
measurement application. As one of StellarNet's 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. The BLACK-Comet-CXR reliably
measures CIELAB & Delta E* values.
StellarNet's BLACK-Comet-CXR colorimeter is applicable for color
measurements of food, beverages, industrial and home liquids, textiles,
plastics, pharmaceuticals, and raw materials.
Color
Measurement Accessories
A fiber optic sample probe is illuminated using a
fiber optic light source (see options below). For measuring the
color of solid samples an integrating sphere,
such as the IC2, can be used in place of the fiber optic
reflectance probe to improve measurement consistency.
The IC2 act as a cosine receptor for irradiance
measurements. In addition, a reflectance fixture
with an integrated light source may be used to measure the color of
solid and powder samples. A
white reflectance standard, such as the RS50 listed below, is
required to generate a reference for subsequent measurement of solid
samples.

SpectraWiz Software
Software is included to provide CIE 1976 L* a* b*
(CIELAB) color coordinate data for measurement and tolerancing. The
L* (L star) is a measure of Brightness. The a* and b* are the color
coordinates that range from -90 to +90 in the CIELAB color space
"circle". For a* (a star), -90=green and +90=red. For b* (b star),
-90=blue and +90=yellow. To perform color tolerancing, a standard
sample is measured and saved for future comparisons. A Delta E*
value is then calculated to show the color differences with other
samples. Double beam and multi-beam color monitors for continuous
industrial process monitoring are configurable by adding additional
channels.
Power and
InterFace
Portable spectrometers include
a USB-2 interface cable and +5VDC power adapter for
120VAC-60H (light sont transformers with
U.S. style 2 prong plugs). For usage
outside the U.S.A., we offer an upgrade to universal power adapters.
If you don't have a USB-2 port, connecting the spectrometer to a
second EPP printer port on your computer is most convenient and
recommended. For portable notebook computers that don't have a USB-2
port or an EPP capable printer port, we offer the PCMCIA card style
EPP interface.
