    Design Lens Lost
AI Thread Summary
The discussion centers on the rediscovery of an aspheric lens design equation that was previously lost. A member located a preserved link to the Thorlabs page containing the equation, which addresses ideal shapes for lenses without spherical aberration. The updated thread now includes the correct link to access the information directly. A screencap of the formula was also shared, adhering to Fair Use guidelines. This exchange highlights the importance of preserving and sharing valuable technical resources in optical design.

Hi all,

I was interested in ideal shapes for lenses and Google popped up this very old thread:
"Mathematical shape for a lens with no spherical aberration"A member named Redbelly98 replied (<link>) with a now-broken link to a Thorlabs page that gave an aspheric lens equation.

Took a minute, but I think this is the page with that equation (on the page's "Lens Equation" tab) safely preserved on Internet Archive:
"Molded Glass Aspheric Lenses: 350 - 700 nm or 400 - 600 nm AR Coating" - Thorlabs
 
Science news on Phys.org
I edited a screencap of the formula (for compactness)
from the ThorLabs web-page, by virtue of Fair Use
bcoz U.S.Code Title 17, Section 107, blah blah blah

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...

Thread 'Pentaprism with magnification, which surface is curved?'

I would like to use a pentaprism with some amount of magnification. The pentaprism will be used to reflect a real image at 90 degrees angle but I also want the reflected image to appear larger. The distance between the prism and the real image is about 70cm. The pentaprism has two reflecting sides (surfaces) with mirrored coating and two refracting sides. I understand that one of the four sides needs to be curved (spherical curvature) to achieve the magnification effect. But which of the...
