Reflectance standard calibration
WebTo effectively measure a fluorescent white sample, we must control the amount of UV energy that is present in the light source. For non-fluorescent materials we follow the standard calibration process that uses a black trap and a white tile. These two calibration tools are designed to calibrate the visible portion of the spectrum only, and they ...
