    You can calculate the focal length of the lens needed if 
you know the distance of the projector from the screen 
(throw) and the size of the screen, that is, the size of the 
image you want. You already know the size of the 
transparency.
    There may not be a standard lens of the right focal 
length available. Of course the easy answer is to move the 
projector closer to the screen if you can.
    Nothing is obsolete if it still does the job.
