I use right angle prisms to make an image alignment.
Let's suppose 1st and 2nd image are the same. The 1st image should be aligned with the 2nd image.
My problem is that right angle prism deviates input ray about 8°. ( Prisms are made of bk7 material which has refractive index = 1.5168 )
Can anyone let me know where and how I must re-arrange prisms( where to add that 8° gap) so that it will eliminate that deviation and the rays of picture 1 and ray of picture 2 will enter the camera in a correct way?
Thank you
