  • What accuracies can color sensors and mini-spectrometers achieve?
    Spectrometers are used as reference devices in color measurements. However, they usually are to expensive and bulky for active usage in most applications. Color sensors and mini-spectrometers are effective solutions in this case. But which sensors and detectors are suited best for specific
  • Accuracy optimization of True Color Sensor solutions for LED color control of multiple LED light sources
    require long-term stable and reliable LED lighting control and regulation methods.  . Image 1: LED feedback control system. A LED feedback control system requires accurate and fast measurements of the current color point. For this purpose a True Color sensor (TCS) is required. Unlike a spectrometer

  • Hubble Unveils a Galaxy in Living Color
    in both "dusty " and "clean " regions of the galaxy. This color-composite image was created from seven images taken with three different Hubble cameras: the Faint Object Camera (FOC), the Wide Field and Planetary Camera 2 (WFPC2), and the Near Infrared Camera and Multi-Object Spectrometer (NICMOS).
  • Spectrometer Introduction - Wide Range of Application References
    the spectrum of stars, planets and comets; automobile industry, measure on-line low concentration of water contamination in oil, measure coating on car glass windows; and biology, to measure chlorophyll concentration and UV absorption, measuring color change and sexual behavior of fish under
  • HR4000 and USB4000 Shutter Mode Performance in Hardware Trigger Mode
    between Shutter mode and Nonshutter mode operation cannot be. used. Common applications that have limitations are the following: • Time Normalized Analysis below 3.8ms. • Absolute Irradiance Measurements below 3.8ms. • Color Measurements below 3.8ms. 210-00000-000-04-1007. 1. HR4000/USB4000 Shutter Mode
  • Conditioning: Is It Really Necessary?
    The spectrometer and its associated software are the key elements in digital color communication. This technology has allowed companies around the world to design, specify, and produce in a repeatable manner to the same set of standards. An issue that is often neglected is that certain dyes shift
  • Spectroscopy and Colorimetry
    , making these objects a metameric pair. This difference depends on the light source and the sensitivity of the sensor or the response of the human visual system. Common color-measurement devices are densitometers, colorimeters and spectrometers. A densitometer measures and computes how much of a known
