Prototype 3

 

Prototype #3

This 3d printed prototype was made at Shapeways

It fits perfectly on the iPhone 4 

 

That one step closer to the final product.  The integration dome is working well and getting good readings.  I think it could be bigger to collect more light for the camera.  We tried to use printed domes, but they were not the correct translucent material.   The dome needs to have 18% light transmission.  Luckily we found stock sheet material that has these exact properties.  We then had to form that material in to the dome shape we needed.
