Our Color and Optical Measurement Calibration Services

Color measurement instruments must deliver reliable performance that ensures product quality, customer satisfaction, and regulatory compliance.

When color and optical measurement systems drift out of calibration, the consequences can include color mismatches, quality failures, customer complaints, and significant costs from rework, waste, and brand reputation damage. The Accredited Labs network provides comprehensive color calibration services to keep your instruments performing within their required accuracy ranges.

Our Process 

Color and optical measurement calibration encompasses the specialized verification and adjustment of instruments that measure color, light, surface appearance, optical density, and spectral characteristics using traceable reference standards with known optical properties. This essential service ensures instruments accurately measure color coordinates, spectral reflectance, light intensity, surface gloss, optical density, and material viscosity across their specified ranges and operating conditions.

During calibration, expert technicians clean optical components, verify zero and full-scale standardization, perform repeatability testing using NIST-traceable standards, and document instrument performance across measurement parameters. Comprehensive calibration procedures address optical path integrity, detector response, light source stability, and measurement geometry to ensure complete system performance. When adjustments are needed, technicians restore instruments to manufacturer specifications, providing documented evidence of measurement capability.

The calibration process follows rigorous protocols established by international standards, manufacturer specifications, and industry best practices, ensuring consistency, reliability, and measurement traceability. Each calibrated instrument receives comprehensive documentation including calibration certificates, measurement data, and traceability information that demonstrates regulatory compliance and measurement reliability for quality management systems.

Types of Color Measuring Instruments We Calibrate

Our comprehensive color calibration services cover the complete spectrum of technologies:

  • Colorimeter Calibration:  Colorimeters provide rapid color measurement for quality control, production monitoring, and color matching applications. Our colorimeter calibration services include cleaning optics and optical paths, cleaning integrating spheres, validating zero and full-scale standardization, performing repeatability testing with traceable standards, and issuing certificates of calibration. We calibrate all manufacturers including Konica Minolta, PCE Instruments, CHN Spec, 3nh, and others across all models from portable field instruments to benchtop production units.

  • Color Spectrophotometer Calibration:  Color spectrophotometers provide comprehensive spectral measurement for precise color characterization, formula development, and quality assurance. Our spectrophotometer calibration includes optical cleaning, sphere cleaning where applicable, zero and full-scale validation, repeatability verification using NIST-traceable color standards, and comprehensive documentation. We calibrate instruments from X-Rite, Konica Minolta, Datacolor, HunterLab, BYK Gardner, CHN Spec, Lovibond, PCE Instruments, 3nh, and all major manufacturers.

  • Densitometer Calibration:  Densitometers measure optical density for print quality control, film processing, and graphic arts applications. Our densitometer calibration encompasses optical cleaning, standard cleaning, zero and full-scale reset, repeatability testing, Delta E measurements using NIST-traceable standards, density measurement verification, and calibration certification. We service X-Rite, Techkon, 3nh, and all densitometer manufacturers and models.

  • Gloss Meter Calibration:  Gloss meters measure specular reflectance for surface appearance evaluation and quality control. Our gloss meter calibration includes optical and standard cleaning, zero and full-scale reset, repeatability testing, gloss verification using NIST-traceable gloss standards at multiple angles, and calibration documentation. We calibrate gloss meters from Konica Minolta, BYK Gardner, Lovibond, 3nh, CHN Spec, PCE Instruments, Rhopoint, Elcometer, KSJ, TQC Sheen, Landtek, and all manufacturers.

  • Light Booth Calibration:  Light booths provide standardized viewing conditions for consistent color evaluation and visual assessment. Our light booth calibration verifies light source spectral output, illumination uniformity, viewing geometry, and compliance with industry standards including D65, TL84, CWF, and other standard illuminants. We calibrate viewing booths from all manufacturers to ensure accurate visual color assessment.

  • Light Meter Calibration:  Light meters measure illumination intensity for photography, industrial lighting, workplace safety, and quality control applications. Our light meter calibration verifies measurement accuracy using NIST-traceable light sources across the instrument's measurement range, documents spectral response characteristics, and provides comprehensive calibration certification. We calibrate light meters from all manufacturers for diverse lighting measurement applications.

  • UV-Vis Spectrophotometer Calibration:  UV-Visible spectrophotometers provide analytical measurement for pharmaceutical analysis, chemical testing, and materials characterization. Our UV-Vis calibration includes wavelength accuracy verification, photometric linearity testing, stray light assessment, baseline verification, and comprehensive performance validation using NIST-traceable standards. We calibrate UV-Vis spectrophotometers from all major manufacturers for laboratory and research applications.

  • Viscometer Calibration:  Viscometers measure fluid viscosity for quality control in paints, coatings, food products, pharmaceuticals, and chemical manufacturing. Our viscometer calibration includes spindle and case cleaning, zero reset, full-scale testing, repeatability verification, accuracy validation using NIST-traceable viscosity standards, and calibration certification. We calibrate rotational and cone-and-plate viscometers from Brookfield, BYK Gardner, PCE Instruments, Anton Paar, Fungilab, A&D Instruments, IKA, Thermo Fisher, Gilson, Seiko, and all manufacturers.
