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.
Claims8
An optical lens having multiple optical axes individually corresponding with a respective refractive combination comprising a first and an opposing second refractive surface, the lens being movable relative to an extraneous optical axis so as to permit selection of a desired refractive combination by aligning the optical axis of the refractive combination with the extraneous optical axis, the multiple optical axes intersecting at a location within the lens.
An optical lens having multiple optical axes individually corresponding with a respective refractive combination comprising a first and an opposing second refractive surface, the lens being movable relative to an extraneous optical axis so as to permit selection of a desired refractive combination by aligning the optical axis of the refractive combination with the extraneous optical axis, the lens further comprising a rotational axis about which the optical lens is movable to selectively align the optical axis of a desired refractive combination with the extraneous optical axis, wherein, in each refractive combination, the first refractive surface is disposed on one side of the rotational axis and the second refractive surface is disposed on the opposite side of the rotational axis.
