Built for performance and reliability, the CM-3700A Spectrophotometer is a top-of-the-line bench-top measurement instrument designed to precisely evaluate the color and appearance of opaque, transparent, translucent, and fluorescent samples. This high precision, versatile spectrophotometer is used to evaluate, reproduce, and help control the color and appearance of samples in a more effective, streamlined process. Its advanced capabilities and unwavering performance enable users to formulate and match color quality standards more efficiently, maintain consistency in each batch of material, and help communicate color seamlessly internally and throughout the supply chain. This makes the CM-3700A ideal for color analysis, formulation, and quality control inspections within laboratory and manufacturing environments.

The CM-3700A Spectrophotometer is compatible with SpectraMagic NX software to record measurements and provide a more comprehensive color analysis, as well as Colibri software to formulate color recipes for various applications and share real-time measurement data.

Features
  • Aperture size options - includes 3x5mm, 8mm, and 25.4mm aperture sizes to accurately evaluate the color of a wide variety of samples small to large in size; automatically detects aperture size and communicates to color analysis software, SpectraMagic NX, for improved user convenience
  • Versatile - precisely measures opaque, transparent, translucent, and fluorescent samples light to dark in color and low to high in saturation
  • Tight inter-instrument agreement - inter-instrument agreement of ΔE*ab 0.08, allowing color values and specifications to be communicated, shared, and coordinated seamlessly internally and throughout the supply chain
  • High precision measurements - unwavering, high precision measurements to maintain consistent results internally and across the supply chain
  • SCE and SCI modes - can easily switch between SCE and SCI measurement modes to accommodate the surface conditions of each sample
  • Long lifespan - hand assembled with quality parts, making it durable and reliable to keep customer operations running as smooth as possible
  • USB connection - conveniently allows users to connect to a PC or laptop
  • Conforms to standards - conforms to CIE, ISO, ASTM, DIN, and JIS measurement requirements
  • Software compatible - integrates with SpectraMagic NX software for color quality control, as well as Colibri software for color formulation and sharing real- time measurement data
