ABSTRACT:
A combined infection shield and calibration or reference target for use with a measuring instrument includes a removable calibration/reference layer. The removable calibration/reference layer has predetermined optical characteristics that can be utilized to calibrate or reference the instrument. The calibration/reference layer may have predetermined reflectance or scattering properties, a predetermined transmissivity to light, or it may have predetermined fluorescence properties. When the calibration/reference layer is removed from the remaining portions of the device, the portion of the calibration/reference layer having the predetermined optical characteristics is irrevocably altered such that the calibration/reference layer cannot be reused. The combined infection shield and target may be attached to a shield holder, which in turn is attached to an instrument. Alternatively, the infection shield and target may be attached directly to an instrument.
