AI Thread Summary
The discussion focuses on the Lensmaker's equation for a plano-convex lens, highlighting the challenge of adapting the bi-convex lens formula, which includes two radii, to a lens with only one radius. When the second radius is set to infinity, several terms in the equation become zero, simplifying the formula. Participants confirm that this simplification leads to a more straightforward expression for the plano-convex lens. The conversation emphasizes the importance of understanding how the lens shape affects the equation. Ultimately, the simplified formula for a plano-convex lens is confirmed as valid.

Can someone help me with the Lensmaker's equation for a plano-convex lens? The formula for a bi-convex lens is readily available but it includes a term for the radius for each of the two curves. A plano-convex lens has only one radius!

Let the second radius go to infinity.
 
Thanks. Does that mean the formula is simplified to the formula shown in simple2.jpeg?

Whether I start with the formula shown in simple1.jpeg or that shown in complex.jpeg, if the second radius is infinity a number of terms are then zero.

Thread 'Simple math model for a Particle Image Velocimetry system'

Hello togehter, I am new to this forum and hope this post followed all the guidelines here (I tried to summarized my issue as clean as possible, two pictures are attached). I would appreciate every help: I am doing research on a Particle Image Velocimetry (PIV) system. For this I want to set a simple math model for the system. I hope you can help me out. Regarding this I have 2 main Questions. 1. I am trying to find a math model which is describing what is happening in a simple Particle...
