  • New Technology Offers Better Choices in Spectrophotometers
    Services Directory. by Michael H. Brill, Ph.D. Ten Tips for Maximum Color Measurement Performance. Although color spectrophotometers are designed to measure specimens both accurately and repeatably, they accomplish these measurements only within tolerances. Spectrophotometers aren 't perfect measuring
  • Spectrophotometers Measure Haze in Plastics (.pdf)
    Our objective is to describe a method for measuring the cloudiness or hazy characteristics of transparent colored plastic samples using Minolta's CM-3500d or CM-3700-d spectrophotometers. A sample with a hazy appearance changes the optical and/or chromatic attributes. Typically, a hazy sample

  • Near IR Spectroscopy in Process Analysis
    in process analysis?. Interest in NIR grew quickly in the 1980s due to the advent of fiber optics, bright light sources and sensitive detectors. NIR also solved some of the difficult sampling techniques characteristic of IR, because NIR optical paths through liquid samples may be millimeters or even

    , and the color-measurement device is generally the human eye. However, the human eye is not as adept as a computer is in distinguishing subtle variations in hue and intensity, because the brain adapts to ambient light levels by correcting for variations. This is called the process of accommodation
