Light path of 1.25" and 2" diagonals

[MortonH]

Can anyone tell me the difference in light path between 1.25" and 2" diagonals? I assume it can vary between manufacturers, but I'd like an idea of the difference.


Thanks

For mirror type diagonals:
From the front nosepiece/ body "shoulder" to the eyepiece "shoulder"
1.25" diagonal = 80mm
2" diagonal = 110mm
Difference = 30mm

Hope this helps

Should be exactly what I needed to know.

Thanks!
