ABSTRACT:
The present disclosure provides for a device, as well as a system and method associated therewith, for, among other things, providing: (i) up to five distinct measurement angles along with an illumination reference channel; (ii) a plurality of illumination sources that provide a focused beam of illumination at specific desired angles of incidence to a sample under target; (iii) a shutter mechanism incorporating a calibration transfer standard; (iv) an internal optical system that is operatively associated with a gimbaled structure suitable to allow vertical and angular conformity to a target sample; and (v) a handheld and operated enclosure incorporating a user interface with a visual display unit complete with interactive navigation means and an activation switch, and a number of surface detecting contact elements operatively associated with the optical system and shutter mechanism.
