CHAPTER ONE
Introduction to the ColorFlex EZ System
The ColorFlex EZ spectrophotometer is a versatile color measurement instrument that can be
used on products of virtually any size, and in industries as diverse as paint, food, and textiles.
The instrument uses a xenon flash lamp to illuminate the sample. The light reflected from the
sample is then separated into its component wavelengths through a dispersion grating. The
relative intensities of the light at different wavelengths along the visible spectrum (400-700 nm)
are then analyzed to produce numeric results indicative of the color of the sample. This is an
objective means of quantifying what was once considered a subjective aspect of a sample’s
appearance—its color.
ColorFlex EZ is available with a large viewing area and a 45°/0° geometry. The label on the
bottom of the instrument provides this information and a unique serial number, which is
outlined below.
Accessories
The following accessories are included with the ColorFlex EZ:
• Calibration tiles - A NIST traceable white calibrated tile is placed at the sample port
during standardization to set the top of scale. The Black Glass is placed at the sample
port during standardization to set the bottom-of-scale, and the Green Check Tile is
used to assess long-term instrument performance during the Diagnostic Green Tile
Test.
• Certificate of traceability for the standard White Tile.
• Tile data sheet - provides NIST-traceable calibrated values for the standard White
Tile and values read at factory for the Green Tile.
• USB cable for connecting the ColorFlex EZ to a computer.
