Patent ID: 8840027

Claim:
A reader for electro-optically reading a symbol, comprising: a housing held by an operator; a data capture assembly supported by the housing for directing laser light having a laser wavelength in a laser light pattern to the symbol, and for detecting return light from the symbol, wherein the laser wavelength is in the range from 630 nm to 740 nm; and an optical element supported by the housing in a deployed position, the optical element being transmissive to laser light of said laser wavelength to enable the operator to view the laser light pattern on the symbol through the optical element in the deployed position, wherein the optical element blocks out all other wavelengths of light from other sources outside of the range from 630 nm to 740 nm for enhancing the visibility of the laser light pattern, wherein the optical element includes a generally planar filter mounted on the housing for movement between a stored position in which the filter lies in a generally horizontal plane adjacent the housing, and the deployed position in which the filter lies in a vertical plane perpendicular to the housing.
