Thank you for your reply. YES, optical alignment system allows two pictures to be viewed simultaneously but it can be achieved more ways. Do you know what method is used in the superior machines e.g.in Shuttlestar machines?

Thank you for your reply. For the first type of the optical alignment, do you mean something like this in the picture below? And can you please explain a little more another form of prism system that is the dichroic mirrored prism assembly?

Sorry...prism. Typically no mirrors.

I'm not sure of that point, just that they are comprised of two 45 degree prisms.

Hi, Can anyone explain how BGA optical systems work on proffesional systems? What optics is used?( optical prisms or mirrors only)

Thanks for the reply. So a mix of two images is made by optics(2 prisms) and ONE camera shows the result? Or there are two cameras and a mix of two images is made in video mixture device?

Thank you for your reply. Are you sure that it should really work as drawn? Or the mirrored ray( blue colour) will go differently because there is a total internal reflection? And the correct path of the mirrored blue ray is like that green ray?

Not like that. Like this. The prism area is a partial mirror. A variable light source at Image 2 is key.

Hi, Clarification...The point I was not sure of was Jane's last post; not Hedgemon's. I was typing while Hedgemon was posting.

One camera is used with typically one of the following prism set-ups: The split prism system, in its most common form, is a cube made from two triangular glass prisms which are glued together at their base using polyester, epoxy, or urethane-based ad
