Avian Technologies Fluorilon™ gray scale targets allow the user to calibrate instruments such as spectroradiometers over a 2 decade range of reflectance, which is well over the typical range seen by a reflectance instrument. The materials are highly diffuse and have little angular dependence and almost no gloss; specular included and excluded geometries will show little difference in reflectance values. In addition to single reflectance targets, arrays of multiple reflectance values (contrast targets) are also available in various sizes and reflectance values.
Nominal reflectances at 600 nm 2%, 5%, 10%, 20%, 40%, 60%, 80%, 99%*
Calibration Calibrated or uncalibrated
Dimensions Square: 2.00″, 4.00″, 5.00″, 6.00″, 10.0″; in Delrin holder with ¼-20 mount, or without mount
*Tolerance is +/- 1% at 600 nm for 2%, 5%, and 99% targets. All others have a tolerance of +/- 2%.
In addition to square targets, we offer round standards in the same material. Custom sizes & sets are also available; contact us to discuss your specific application.
