FTS Acrylic Whiteness Standards

Avian Technologies is excited to announce that it is the sole manufacturer of the line of acrylic fluorescent standards formerly known as CCS (Color Control Systems) standards. Developed by the late Professor Frederick T. Simon, these standards can be ordered in a wide range of CIE whiteness, and are also available in high gloss or diffuse surface treatments. The sets described in the table below represent only a few variations. Please contact us to customize a series that meets your requirements.

The fluorescent properties of the FTS tiles make them ideal for applications involving the measurement of fluorescent whitening agents (FWA) common in office papers. In measurement it is always good practice to use similar standards whenever possible. See the plot below for a direct comparison of office paper and AT-FTS-15a.

Comparison of Office Paper and AT-FTS-15a
Standard office paper and AT-FTS-15a, each measured under illuminantion approximating D65. The plot shows very similar properties, especially in the critical absorption regions (350-400nm) and emission regions (400-475nm). The 15a is an ideal reference standard when paper with this amount of FWA. The range of available FTS tiles means that there will be a standard available that will closely approximate the fluorecent properties of your paper.
