Patent ID: 8729917

Claim:
An inspection device comprising: a carrier having a central passage through which light may pass and a window positioned over an upper opening of the central passage, the window being substantially transparent; a housing, wherein the carrier is disposed within the housing and is reciprocable between a retracted position and an extended position; an actuator positioned within the housing such that at least one actuating surface of the actuator is actuatable to bear against at least one bearing surface of the carrier, the actuator being actuatable between a first position in which the bearing surface permits the carrier to remain or return to its retracted position and a second position in which force is exerted by the at least one actuating surface against the at least one bearing surface of the carrier to move the carrier to its extended position; and a focusing mechanism disposed in the central passage of the carrier, wherein the focusing mechanism includes a flexure having a middle portion that is coupled to a top section and to a bottom section by resilient couplings, the top section and bottom section being on opposite sides of the middle portion.
