The set consists of ten 1.25" diameter Lucideon Color Standards Series II (CCSII) tiles in holders with covers in a water resistant box. The tiles cover the color gamut from violet to red; nominal reflectance data is shown below.
These color tile sets are a less expensive option from the CCSII set (formerly known as CERAM Series II or BCRA tiles). The size and shape make usage convenient, especially for small spot and hand held instruments.
The sets are sold uncalibrated, or calibration of the sets can be provided in our NIST/NRC traceable laboratory at all common instrument geometries (available geometries include 8:T, 8:D, (also D:8 and D:0)) CIELAB data are also available.
