Like macdaddyjaz above I have just modified a Logitech C615. The most difficult part was to desolder both pins of the auto focusing lens unit without to slosh around any liquid solder. Read the very useful instructions of Datapanic:http://www.cloudynights.com/ubbthreads/ ... art/1/vc/1
...and here the special photo what I mean with 'difficult part':http://www.cloudynights.com/ubbthreads/ ... %20mic.jpg
To my photos:
1. The new C616 in an ABS plastic case, wall thickness 2mm. CS- or C mount lenses can be used. Latter must be used with an additional and under item 4. mentioned 5 mm extension adapter.
For the 'large' sensor of this cam a megapixel lens is recommended. And specially for SL scanning it should have a focal length of about 12mm. E.g. this one:http://www.bhphotovideo.com/c/product/8 ... _Lens.html
2. The camera from the back side. I have sawed a long 3 mm wide slit to enable the insert of the USB cable without to remove one of its both plugs at the cable ends. But it is absolutely necessary to cover this slit afterwards to avoid any stray light from the back. This can be done with dark adhesive tape or with the plastic part itself which was cut out. Also the blue LED on the cam board must be covered by a drop of dark paint. See the next photo.
3. A detail photo of the cam board, sensor side. The original auto focus lens is removed. You can clearly see an IR cut-off filter just in front of the sensor. Its diameter: 10mm, 1mm thick. The free and hatched marked areas can be used to fix the board on carriers. The camera board is 55mm x 21mm.
4. You can see the metallic adapter ring, stuck by a 2 component epoxy adhesive. These 5mm extension rings are cheap standard items, normally used to adapt a C mount lens to a CS mount camera.
The board will be fixed on two small plastic blocks. From the front M2 screws are holding the blocks. For fine adjustment of the cam board in x and y direction in relation to the centre to the new lens it is of advantage to drill the holes inside the plastic blocks bigger than 2 mm, best 3-4 mm and to lay a washer below the 2 mm nuts.
At the bottom of the case I have glued a 5 mm thick plastic part in which I have cut two threads, metrical 6 mm and ¼ inches.
5. Camera board mounted on the plastic blocks.
Edit (Febr 2014):
Sorry, if I haven't clearly mentioned that the original built-in IR cut-off filter cannot be used for the modification. I had bought one from Sunex Inc.:http://www.optics-online.com/irc.asp
