An optical scanner having enhanced item side coverage which scans all six sides of an item and an intermediate side. The optical scanner includes a scanner housing, a first optics assembly within the scanner housing including a horizontal aperture, and a second optics assembly including a second housing within the scanner housing including a substantially vertical aperture. The first and second optics assemblies are capable of scanning six sides of an item. At least one of the first and second optics assemblies additionally generates third scan lines for scanning an intermediate side of the item.

An improved detector assembly restricting light striking a detector within the assembly to a relatively narrow bandwidth and techniques for fabricating the same. A pliable material is impregnated with a coloring agent selected so that the material provides a filtering effect admitting light within a range including a predetermined wavelength, with the wavelength having a value based on a wavelength of a laser to be employed with the detector assembly. The pliable material is shaped so as form a capsule enclosing a detector, with the capsule including a hemispherical lens element as an integral part of the capsule. The hemispherical lens element is coated with a filter coating selected to provide a filtering effect complementary to that provided by the coloring agent, such that the combined filtering effects provided by the filter coating and the coloring agent provide a bandpass filtering effect.
