Product Announcement from StellarNet, Inc.
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.
Free 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.
