Patent ID: 8502967

Claim:
An apparatus for optical inspection, the apparatus comprising: a platform extending in a first direction; a transmitting unit for transporting at least one carrier in the first direction from an input port to an output port thereof, each of the at least one carrier to support one of at least one object to be inspected; a first detector disposed above the platform and extending in a second direction orthogonal to the first direction for inspecting the at least one object on the at least one carrier, the first detector including a first scanner extending in the second direction between the input port and the output port, and a second scanner extending in the second direction between the first scanner and the output port, the first scanner including a plurality of scanning units arranged in the second direction that are sufficient to cover a width of the at least one object in the second direction; a first roller set between the first scanner and the input port to apply force onto a surface of each of the at least one object: a second roller set between the second scanner and the output port to apply force onto a surface of each of the at least one object; and at least one of a first angle adjusting means to adjust an angle of the first scanner with respect to the normal direction of the surface of each of the at least one object or a second angle adjusting means to adjust an angle of the second scanner with respect to the normal direction of each of the at least one object.
