Lucideon Ltd ceramic standards - BCRA Series II tiles* - are popular standards for color calibration in the US and abroad. These standards can be used to calibrate color spectrophotometers in both hemispherical and directional/directional geometry. Avian Technologies Lucideon BCRA sets consist of fourteen 2″ tiles (the standard Lucideon BCRA set plus a black and a white tile), mounted and sealed to prevent effects of humidity. Custom sets are available.
If you wish to assure an instrument stays within calibration but do not have the time it takes to run a full set of Lucideon BCRA standards, it is suggested that a single tile with some spectral structure be used**. We have found that the cyan tile is the best tile for this application within the BCRA Series II set.
In addition to the cyan tile, all tiles in the BRCA Series II set are available individually. We offer tiles either calibrated or uncalibrated, made to the same specifications as the set described above. The tile is sealed in a Delrin holder and comes shipped in a hinged plastic box.
