I still hadn'd responded to your original reply, but now I have to. You actually managed to fix it even though the software is now falling apart! Thanks.

We use telecentrics when needed or when they make things simpler, yes. Often, though, they are either not feasible or simply not needed. And they don't really help with depth of field, except by...
All this is waaaay above my knowledge level. I was just trying to figure out how to estimate positioning tolerance in a machine vision system, with lens data I have available.
m_d = (m/p + 1) * f / (u_d - u_ep) is a continuous function for u_d > u_ep. And it's not difficult to show that m_d = m when u_d = u. Just substitute u_d=u=(1+1/m)*f and u_ep=(1-1/p)*f.
I...
Also, after a good night's sleep, it occurred to me that (m+p)/p is just the bellows factor so the new eq. (96) can be represented as:
k_r = m / (1 + m/p) * |x_d| / N
This is practically...
Magnification at the focused point depends only on the principal plane, this is correct. However, principal point is not the center of angle of view, entrance pupil is. AOV is what determines the...
It appears I made a mistake so my results in previous post are wrong:
m_d = (m/p + 1) * f / (u_d - u_ep)
u_ep = f * (1 - 1/p)
With this, the result becomes:
k_r = k/m_d = m*p/(m+p) * |u_d...
Hello, I've been reading Depth of Field in Depth, and it has been of great help for my purposes.
However, I may have stumbled upon an issue, unless I'm wrong. Equation 96, "relative blur" with...
