Re: overlay computer display on view through binoculars

Basically the problem is fairly trivial.
What you want is to focus the computer display to the focal plane of the
binocular's focal plane.  Introduction of the light to the binocular light
beam is by a piece of glass at 45 degrees to the axis of that beam.
Try this with a simple telescope first and you will see how easy it is to
do.  I'll note that the prisms in a binocular invert and revert the image so
that the light coming out of the eyepiece is of the same directions as the
original scene while the simple telescope will be upside down and reversed
right to left.  You can use a slide glass cover (thin glass) for the
beamsplitter as you will have plenty of light available from the computer
display relative to the incoming light although you may want to get a better
beamsplitter that reflects 50% of the light if you are having problems with
that but your view will be dimmer in that side of the binoculars.

Hi Bob,

This sounds like exactly what I'd like to do, I tried it in a very simple way, but the problem is that the computer display is blurred, how do I get it in focus at the binocular's focal plane?
