Sadia,

The photo seems to show some optics which look like its probably a prism, if so, I guess it bends the light off to the periphery and in doing so lengthens the light path to the same length as the main chip, hence achieving focus.

Guesswork until we see more.

Paul,

The QSI simply has an OAG prism in built as a guider port and you add your own guiding system, whereas the SBIG has a fully integrated internal guide camera but now placed in front of the filter wheel which also works in conjunction with all of the SBIG functionality - eg Adaptive Optics, pulse guiding etc etc
No copying there.
