Lens Holder

Posted by vansmith on 22 Apr 2011 at 00:41 GMT

Thanks to Randy Barnes of the North Carolina Center for Engineering Technology, in Hickory, NC, I now have two holders for the 1mm spherical lenses. Randy fabricated these today using the Center's Rapid Prototyping machine and the design we developed in SolidWorks. These holders snap into the protective cover for my Samsung Galaxy Fascinate cellphone from the inside of the case. A small flange in the holder acts as a retainer.

As soon as my spherical lens arrives I will begin testing to check focal length. I have photos, but have not found the procedure for posting them on this discussion board.
