Color Measurement

Color measurement is a critical, objective quality parameter for many industries including manufacturers of chemicals, cosmetics, food products, ink, paint and coatings, paper, petroleum, pharmaceuticals, plastic, and textiles, as well as to companies that provide services such as graphic arts and printing. Color often plays a major role in the acceptability of a product. Since visual color judgments can be affected by a wide variety of factors, instrumentation to measure color provides a consistent method of color management and quality control. Correct color measurement has become even more critical, with manufacturing geographically dispersed on a worldwide basis. Standardized processes can guarantee color integrity and fidelity throughout a worldwide supply chain. Color management tools and systems offer the advantages of predictability, reproducibility and consistency that all translate into profitability.

Color can be measured utilizing either colorimeters or spectrophotometers. Spectrophotometers measure the ratio of light reflected or transmitted from a product to that from a known reference standard. Despite constant improvements, simple and inexpensive colorimetric methods can only offer incomplete simulation of several types of light and lack the spectral remission values and measurement of metamery. These methods can not offer the absolute measurement accuracy available with spectrophotometers.

Headwall Photonics is the industry's leading supplier of high volume original holographic diffraction gratings and spectral modules for most of the leading companies in the color measurement industry. Only original holographic gratings offer the high efficiency and low stray light needed for accurate spectrophotometers.

Process Monitoring

Growth has been rapid in the use of rugged spectroscopic methods to monitor industrial production processes. These innovative instruments are at work both at-line and on-line in all types of production environments. They offer cost-effective, non-destructive, non-contact, high precision and instant in-situ measuring capabilities for the scanning needs of chemical, food, agriculture, pharmaceutical/ nutraceutical, polymers, cosmetics, environmental, textile, petroleum and mining industries. For these applications, spectral modules and detectors are embedded into manufacturing equipment to monitor processes and control production.

The most common applications are for monitoring, regulating and controlling processes; following the progress of chemical reactions, fermentation or mixing processes; and checking the purity of final or intermediate products. The marriage of electro-optics and microprocessors is bound to result in revolutionary instruments and techniques that will benefit production technologies.

Quality Control

Quality is the ability of a product or service to satisfy a stated need. Control is the ability to verify by comparison with a standard or by other experiments. Quality Control is concerned with understanding what constitutes an acceptable product, selecting production methods that assure accuracy, designing ways into the production process to test or compare against a standard, and then using the knowledge gained to impact performance. Each industry has its own unique standards and methods of testing but there are tools that offer cost-effective, portable, non-destructive, non-contact, high precision and instant in-situ testing capabilities across many industries.

Many of these tools use spectroscopic techniques. Spectrometers can measure the light absorbed, reflected or transmitted from a product to that from a known reference standard in order to generate, measure, and compare unique spectral signatures. Spectroscopic techniques are being used to establish quality control parameters for everything from specialty chemical and pharmaceutical production to laser, semiconductor, and optical component characterization. As the demand for meeting quality standards increases, more and more companies are building industry-specific spectroscopic instruments to meet these needs.

Environmental Sampling

The threat of bioterrorism, coupled with increased pollution control legislation has increased the demand for environmental sampling, testing and monitoring equipment exponentially. Optimized environmental sampling methodologies combined with ultra sensitive analytical methods are used to determine extremely low levels of contaminants. Sampling technologies are used for all major environmental matrices: water, air, soil, biota, solids, sludges, and liquid wastes. The most significant and critical part of sampling programs is the high sensitivity analytical detection and measurement technology. Decisions involving human health and environmental impacts that potentially may involve large sums of money or national security need to be based on accurate data.

These technologies are continuously undergoing developments to improve sensitivity, accuracy, precision, and cost effectiveness. With advances in remote sensing technology, coupled with the availability of low cost sensor technology, environmental sampling applications hold great promise.

Hyperspectral Imaging

Imaging spectrometry or "Hyperspectral" imaging is a relatively recent development that makes possible quantitative remote sensing three dimensional areas such as the Earth's surface or even manufacturing production lines. Broadband, high resolution imaging spectroscopy has evolved into one of the most powerful technologies in the field of remote sensing and industrial inspection. Broadband hyperspectral imaging spectrographs are capable of spatial and time-resolved measurements of the composition and distribution of emissive, reflective, or transmissive sources for ground, airborne or space borne applications. Hyperspectral imagers offer an extremely powerful tool and have been used in areas such as:

  • Environmental and conservation applications - Oil spill monitoring, fire damage assessment, vegetation stress, canopy studies, pollutant dispersal, wildlife monitoring, precision farming
