INDICIA READING TERMINAL INCLUDING OPTICAL FILTER

摘要

The present invention discloses an indicia reading terminal that is operatively configured to decode visible and non-visible decodable indicia. The terminal comprises an excitation illumination module for illuminating the decodable indicia with light that has a selected wavelength so as to permit the decodable indicia to emit light. The terminal also comprises a filter module with an optical filter that has filter regions configured to pass the light of certain wavelengths. The terminal also comprises an image sensor module with an image sensor located so as to receive the light emitted from the decodable indicia from the filter region. The terminal can decode both visible and non-visible decodable indicia without substantial reduction in the depth of field of the terminal.
