A scaled series of eight white fluorescence standards is available from Labsphere as the exclusive agent of Frederick T. Simon, Inc. FTS white fluorescence standards are the industry standard for instrumental and visual reference in the paper, plastic and textile industries.

The white fluorescence standards are available individually, or as a set of the eight standards, numbered 9 through 16. The number increases according to the amount of "whiteness" of the standard. The white standards are formulated with an opacifier and a fluorescent whitening agent (FWA) molded in an acrylic plastic. Standards numbered 9 through 12 are made to approximate the Ciba-Geigy Plastic white Scale. Numbers assigned to the newer white standards indicate a general relation to the earlier scale, with numbers above 12 indicating a higher concentration of optical brightener. The amount of fluorescence obtained from this composition allows for a direct comparison to the evaluation of white paper, plastics or textiles, without the need, to extrapolate comparison of very bright materials

The standards are available in either a glossy or matte finish, and are specially coated to promote scratch resistance. The standards are extremely stable and durable, and are easily cleaned by using a mild liquid detergent solution and rinsing with distilled water. Each standard is housed in a durable delrin holder with a protective cover. Typical data is included for each standard.
