ABSTRACT:
An optical lens is disclosed that is suitable for use in a line scanner or analogous device. The lens has multiple optical axes individually corresponding to a respective refractive combination comprising a first and an opposing second refractive surface. The lens is movable, preferably by rotation about an axis, relative to an axis of light propagation so as to permit selection of a desired refractive combination by aligning the optical axis of the refractive combination with the axis of light propagation.
