Abstract:
1. A goniometric spectrophotometer comprising: a housing; a user interface incorporated with the housing; a shutter mechanism operatively associated with the housing; an optical system in optical communication with the shutter mechanism and including a measuring interface; and a power source operably coupled to the shutter mechanism and optical system; wherein the optical system provides at least five distinct measurement angles alone with an illumination reference channel and includes a plurality of illumination sources; the shutter mechanism includes an actuating element for activating and controlling the shutter mechanism; the actuating element is a rotating member operatively associated with a cam mechanism, which in turn, is operatively associated with both a pair of shutter elements and a suspension element; and the suspension element accommodates the optical system so as to enable the measuring interface, which, in an inoperative state, is enclosed within the housing, to extend or project from the housing so as to make contact with a target sample via three or more contacting elements.
