description An apparatus configured for determining transmittance of a photochromic optical article including at least one photochromic material including a housing defining an interior configured to receive the optical article, the housing including a holding member to hold the optical article at a predetermined position, at least one source of actinic radiation configured to radiate actinic radiation into the interior of the housing and activate at least one photochromic material in the photochromic optical article, at least one image capture device configured to capture image data of the photochromic optical article, at least one backlighting unit positioned beneath the holding member, and a control unit operatively connected to the at least one image capture device and the at least one source of actinic radiation.
