Abstract
A portable dataform reader includes a large F# optic assembly that provides a working range from about 2.5' to at least 8.5' in front of the reader while maintaining a broad field of view. The reader is capable of capturing a high signal to noise ratio image in under 0.01 seconds thereby making the reader highly tolerant to hand jitter. To accommodate the large F# optic and short exposure period, the reader is provided with an efficient high intensity uniform illumination module.
