I tried this again just now and no way will it register a barcode through
the case of a CD.
The spot of light created by my wand is bright and sharp only very close to
the tip, just 1mm away it's already diffuse and dim.
Is the tip of your wand still a smooth lens shape?
Do you really want to answer such a question? :-)
Joel.
