The sites say Focal Length is 12mm. As most of my scans are between 40-120mm, I have a table tripod set at about 1 foot away from the turntable. The projector with the 4+ adapter seems to have enough focus to work at this distance.
I am rebuilding now to add the second camera, create a blackbox with Black 3.0 paint and such. Hardest is redesigning the projector wedge for the addition of dovetail use.
Hi, i have some questions about small objet scan...
1) which scan configuration panels are you using to scan very smal objects (es: 0.5-2 cm)?
2) what vertical angle do you use between the camera and the projector? May i need to calculate it ?

Two main parameters are important for scanning components ( any size of components).
The size of projected image on a component and the size of the image that is taken for use in the software.
Both must be proportionate.
The image projected on the component should be as close to the size of the component.
The same goes for the image taken.
After all you will find the right size of colibration panel.
About vertical angle : it completely depends to your hardware and the software that you want to use. ( dls has minimum triangulation angle and i use it.)

Narmella.
Sorry but...what is the dls minimum vertical triangulation angle ?
